Replacing the Fuel Pump (Post #626) October 2, 2023

Fuel Pump Swap

In my previous post I talked about the fuel pump and it’s lack of suckage of fuel to make the Big White Bus go down the road. Or more importantly in the short term, get out of the shoppe so I can proceed with the rust repairs.

I ordered the fuel pump from Atlantic British. As I’ve said earlier. If you order from them the part will not officially ship until the day after the first business day in which they receive the order. So if you order on Saturday, they will see the order on Monday, and it will be picked up on Tuesday. Then it will be in transit. For us here in the central southern plains that means a minimum of 6 days to arrive. I think I got this one in 7 days. I’ve come to accept this as the way it’s gonna be. Since the Range Rover is not my daily driver this does not upset me anymore. It just takes extra planning when you need something.

Removing the derelict pump is pretty easy. Turn the ring first. This may take some tapping with a screwdriver and a hammer. Take it easy and take your time. Don’t damage the ring.

The second step if it wasn’t your first step is take the fuel lines off. You will need a pair of 15mm wrenches. Once the lines are out of the way you can rock the fuel pump back and forth while pulling up. It will eventually come up.

The “bowl” will have fuel in it commiserate with how full the tank is with petrol. Pour this out while the fuel pump is still over the tank opening. Be prepared to clean up some petrol if it spills.

Reassembly is a reverse of the process. The most difficult of the tasks is getting the rings of the seal past the tank opening. You can gently coax it past the lip with a flathead screwdriver and steady pressure pushing down on the pump.

Is there a way to use a lubricant…maybe, I didn’t research that. I’ve never used lube for the install, so its not necessary for success.

Take it easy with the float and its electronic bits. Don’t bang it around.

That’s about it for the swap. I need to test the pump and get the the BWB running again. I’ll give it some test cranks to get fuel back up to the fuel rail then reinstall the plugs and fire her up. If I’ve sorted everything we should have a running Range Rover.

Thanks for ready and Happy Rovering.

The Big White Bus Will Not Start (Post #624) September 18, 2023

Fuel pump

Well, awesome. The Big White Bus won’t start.

I have fired it up once since I parked it in my newly constructed shoppe 5 years ago. I guess I should have expected there would be “issues”. But I wasn’t expecting the issue to be this one.

Mr. Fisher came over and we diagnosed the issue. We started with checking the power at the pump. As you may be aware, when you turn the key over it powers the pump briefly. So if you just “turn on the key” and go back there to check the voltage you won’t find any. That’s why it takes either some seriously creative use of a volt meter or you get one of the bestest friends to come over and turn the key for you. We had voltage all the way through the wiring harness.

We then confirmed we have spark from the ignition system. I pulled the number 1 plug and with a screwdriver I grounded it and watched for spark. You can buy a fancy spark tester, matter of fact I think I own one. I have no idea where it is though. Spark confirmed.

So we have two of the three things (Meatloaf would say that “ain’t bad”) to make the vehicle run. Air and Spark. Now why aren’t we getting fuel.

I pulled the gas line off at the regulator on the back side top of the engine and had Mr. Fisher crank the ignition. We should have had gas squirting out if it worked. It did not. This fit with me NOT hearing the pump run when the ignition was turned over.

The only thing left was to pull the fuel pump and do a visual inspection. What I found was not expected. I said, “Wow.” a lot in the video. There were several parts that were obviously degrading due to being submerged in petrol for so long. There was visible rust on the steel parts as well. Generally the pump was in a terrible state. I was not aware that petrol would do that to those parts. The only gas I ever put in my Classic is 100% real gas, unless I am in Texas where they only sell ethanol (at least the last time I was buying gas there). You would expect ethanol to eventually separate and turn to water. You can read all about that on the Road Guardians website.

I will be replacing the fuel pump and have ordered the part from Atlantic British. I found some that were cheaper on Amazon. But my skepticism and need to have it delivered before next October weighed heavily on my decision where to purchase. The pictures all looked like the pumps were manufactured in the same place. Same white plastic. Same blue plugs.

If you look on Amazon you’ll see the pumps look like the same ones. If I had unlimited funds or sponsorship, I’d buy one from everyone and do a side-by-side comparison.

All this “BUY IT NEW” has me thinking about what this would cost if we just fixed the pump. All you need to do is replace the pump in the collector can (that bottom part). I’ll do a post about that in the coming weeks.

So…do I drain the tank too? If the gasoline HAS turned to varnish I should probably put some treatment in there. I’m thinking I’m gonna add a silly amount of STP Fuel Injector cleaner in that tank. I can say, WHEN I get it running It will run for quite a while before I shut her down. I want to give the truck plenty of time to dislodge any crap in the fuel lines. I’m also guessing I’ll need to swap the fuel filter too.

If its not one thing, its another. It really, never ends.

Mr. Fisher also brought over his Viair Compressor. We spent some time looking at it and checking out all its features.

SCARR – Day Three (Post #479) 4/6/2014

Day Three came with the sun shining and the air a bit on the chilly side. As soon as the sun came up it warmed up nicely. Our plan for the morning was to run some trails.

Photo0012

I got dressed in my Rover Cannibal shirt and cooked up some breakfast. We knocked down breakfast and went up to the main pavilion to meet the other drivers.

I found the other drivers very ready and after learning Jacob Dearborn drew the beginner group. Jake as he was called was very nice young man and had a course sorted out. We fell in behind a great couple named Max and Diane and their Series. They had owned it for twenty years if I remembered that correctly. We got the CBs set and off went.

Air Idler Valve Replacement Parts (Post #443) 2/5/2014

Air Idler Valve

There is a great post on the Land Rovers Only Forum that has compiled a great collection of the part numbers for the Air Idler Valve. The part is very pricey if you source if from the major Land Rover online sites like Atlantic British and Rovers North. Those are the two I use, there are others as well.

The part is a common GM part for Chevy Astro vans and S-10 pickups. You can read the post to get all the part numbers and then you can source the part from your favorite provider.

http://www.landroversonly.com/forums/f8/idle-control-valve-idle-problems-get-know-1843/

It’s basically a reprinting of the great stuff found on Rangerovers.net at this link with even more part numbers.

Finding parts for 20-year-old Range Rovers is getting harder and harder every day. Have you looked for a fan resistor kit lately? There are none to be had presently.

Broken Bits (Post #431) 1/6/2014

During my recent repairs of radiator cooling fans and power steering hoses I came across a couple of broken bits. While discussing the electric cooling fan project with the Evil German Dude we noticed the belt that drives the air conditioning compressor was very loose. So while I was under the bonnet for the hoses I thought I’d just sort that out. I didn’t have the replacement hose and it was New Year’s Day so there was no way to get the hose.

I got the pulley in place and began tightening the bolt on the belt tensioner. It never got tight. At some point I decided something was not right at all. At first I figured the bolt was stripped. That has been my experience in the past so my brain naturally went to that first.

I removed the bolt and the bracket and found…
it was broken. Wow. That is disappointing. As you can see in the picture above there are two of these on a Range Rover Classic 1987-1994. The 1995 model has a spring driven unit. This spring driven unit is common to most “modern” cars. This friction method is serious old school. I didn’t say better, I said old school.

I knew finding this part was going to be a nightmare. I immediately called Paul Grant. He is a master of parts and he told me he thought he had one in inventory. I ordered it. It should be sitting in my mail box when I get home today. According to Paul, these are threaded on opposite sides so the one that works for the AC belt will not work for the water pump belt. I’m guessing this is going to added to the list of parts I pull from Range Rovers I find in the breaker’s yards. If you are looking for parts I highly recommend Paul. Stop by his eBay Store and buy something.

The second wasn’t really visible until I had the belts out of the way. Some how the Oil Pressure Switch lost its spade connector. I had noticed a couple of wires loose but was unsure where they went. The spade end doesn’t look like any thing I’ve ever seen before.

The oil pressure switch is found on the side of the engine right where the oil filter is screwed on. I know I’ve changed my oil at least once recently and I should have noticed this but didn’t.

I did find an interesting thing when researching parts sites. Rover’s North lists this part with a really great diagram of it’s identification and location. It also lists for 54.95$(US). However on the Atlantic British site it lists for 7.95$(US). On the Rovers North site similar ones for Discovery II’s also list for 8.95$(US).

I find that a helluva difference in price. I’m almost afraid to ask why. I think I’ll order the 7.95$(US) one from Atlantic British. I’m running out of funds for this round of repairs and I still need to purchase some oxygen sensors.

In my quest for improving the gas mileage by swapping to electric fans I will need to only change one variable at a time. There are potentially four things I believe I can do to improve gas mileage:

  • Remove roof rack (this one is obvious)
  • Replace oxygen sensors (when they begin to fail you will notice fuel use go up)
  • Replace my mechanical fan to electric fans (increased torque and horsepower)
  • Reinstall the air dam (another obvious one)

For the sake of the scientific process I think I’ll change only one variable at a time. I can run a couple of tanks of fuel and get a few MPG readings. I’ll report them all back as soon as I get the data.

Thanks for reading,
You are driving a brick what do you expect your gas mileage to be?

Brake Caliper Failure (Post #364) 7/2/2013

I’m pretty sure that should be dry.

Look what I found. No, not the rust on the splash guard, I expected to see that. The left front brake caliper is leaking. I’ve been hearing a pop on that side ever since I replaced the left rear brake caliper. I was just about ready to send the old gal to the shop for some fresh springs and air conditioning and then this.

I rebuilt all the calipers about three years ago, or was it four? I had trouble with the right rear staying together so I replaced that caliper with a “professionally” restored unit. I’m pretty happy with having 197,000 miles and one rebuild before a replacement for this part.

This may explain the ABS problem I’ve been having of late. When the brake is depressed (pushed down, not emotionally upset) it is hard (as expected) and is stopping but as the brake continues to be pressed it the braking really picks up and decreases the speed very quickly. That tells me something is not quite right time for a replacement.
More after the jump….

Upside down, stamped on the front axle.

When ordering a brake caliper you will need to know your axle number. My 1993 Range Rover LWB is axle number 57L03581A. This will tell the parts man which caliper to send you. The differences are also noted by the type of bolt used to mount the caliper to the axle. Either a 7/16th bolt or a 12mm 12 point head. I’m sure if you pull yours off and inspect the bolts you’ll know which one to order.

I’m looking all over the internet for the part. Rovers North has a unit for 149$(US). Atlantic British has one listed for 199$(US). I’m hoping for a price match. There are some other units available under a hundred dollars. One was “out of stock” and the others did not give me any confidence in who I was ordering from. These are brakes (read that as mostly important) so I’ll stick with companies I’m familiar with.

My grand kids came over while I was researching parts. While their dad and mom ran errands and I was awaiting a response on a price match request from Atlantic British we ate Jell-O and made funny faces. You might say I was encouraging them.

At this point I’m wondering when the caliper will arrive, what with the Independence Day holiday being mid-week. I’m too cheap to have it over-nighted. And when I’ve asked for “priority shipping” it always seems to arrive on the day it would have if I just order the “whenever you get around to it” shipping. If it arrived on Friday I could work on it that day. Saturday is out, Sunday would work but I’m not sure it will arrive by then. So I’m looking at a weekday evening.

Phone rings….
Bully for me, it looks like Atlantic British is going to price match for me. So I got that ordered and I’ll be ready to swap it when it finally arrives. I always enjoy talking to Eric at Atlantic British. After we briefly kibitz and share a joke about my new credit card number and being on a budget, he says it will be here Monday or Tuesday. Indeed the Independence Day holiday has things mucked up a bit.
Thanks Eric (and AB) for the price match.

I told Mrs. OkieRover that I thought I was getting close with the repairs. I’m guessing that was probably in vain. The circumnavigation of Oklahoma is still in the works, with every repair I grow more confident. The Big White Bus is a twenty year old British automobile and I’ll probably have something to work on every week until the rust wins the battle.
