Taking fuel tank down . Replacing pump
Looks like pump is shot out. Got to remove the tank
I hear is a pretty nasty time consuming job Could anyone post the procedure It doesn't looks like too much work. Or I wanna see it that way 😁 |
Make sure its not just the fuel pump relay. Its the box under the hood next to the battery. Mine went out a few years ago.

Relay is good . I checked and is clicking and also switch to another relay still no fuel
Thx |
I believe the straps are just one nut each if I remember correctly. Make sure it is as empty as it can be and place a jack with a piece of wood or something underneath to spread the weight and slowly lower it down. Once you can reach and see up there you can disconnect everything. I also unscrewed the filler neck from the sheetmetal so that could come down on it's own.
|
I wonder if you remove the rear wheel house liner how much better you can see and maybe even reach in to get at certain things to disconnect easier. I think I've read someone saying that before.

I just replaced my fuel pump. It's can be done with tires on the ground, but it's a lot easier with two people and a lift, especially if you have not removed the fuel.
You will first need to remove the tank guard. Depending on your clearance with your wheels, you might need to lift the truck so that the guard will clear the rear axle in order for it to slide out towards the back of the truck. Next you disconnect the fuel lines at the front of the tank. Also, disconnect the inlet hose at the rear of the tank and both the pressure sensor and fuel pump connections by reaching up and over the top of the tank from from the center of the truck Next you will want to have jack stands either on the front or rear, and a floor jack on the other side. Remove the fuel tank straps and continue to lower the tank between front and back slowly and carefully. Again, a good siphon job is worth the extra work to ensure this last part goes smoothly otherwise the weight of the gas is dangerous to work with, without the adequate space under the truck. Get the tank on the ground and slide it out from the rear just as you did the shield. |
Sounds like the most critical part is removing as much gas as possible
Well, of the 90% Im running with an empty tank this time is more than half tank full Otherwise wouldn't be fun Thank you all for the instructions. I will do it this weekend Btw the pump I get is a Delphi . Looks like this is what most people use |
Yeah, I would not go generic on that. The original lasted 12+ years, I'd not want to take the chance of having to drop the tank again soon just to save $50.

Thanks for the inputs ... I didn't understand. Is the pump made by Acdelco or Delphi make it for Acdelco
I couldn't find online an Acdelco fuel pump This one comes in a Delphi box Will look into the fuel pressure. Thanks for the advise |
The part numbers I have are 19331955 and AC Delco MU1423. I'm not aware of a Delphi part number; however, I do know they make many parts for the H2.
|
Thank you for pointing the right direction
Just made the return for the Delphi and got the ACDelco . It was only $80 more Also the Delphi was different than the one posted here a few days ago . Ir was all plastic Feels very cheap https://cimg7.ibsrv.net/gimg/www.hum...3bec9ef2a0.jpg |
I am going to be taking my tank down in the near future? Is it metal or plastic? If metal, is rusting a problem? thanks
|
yes rusting is an issue. i think that is why some manufacturers make it in plastic.

https://cimg6.ibsrv.net/gimg/www.hum...a2b7ecfe27.jpg i return the Delphi pump to get the Oem but also noticed the pump on the box and every pump Insee online was different than this one . The support to the bottom are plastic . I dont know if they changed the model but this pump looks very cheap made |

Now I know why this job is so time consuming
Try for hours to remove the filler gas line . The hose is like welded to the pipes Anyone knows a better way to remove it |
You should be able to twist that filler line to break it loose, then pull directly from the tank.
|
Ive been looking for the new lines to replace since this one feels old but cant find it ..
I will.try again tomorrow twisting and pulling hard . |
