The only thing you should need is the engine size. Any GMC motor can be used in many vehicles.

You really want to replace the fuel pump and not the whole sending unit??? Here is how it's done if your in to getting your hands dirty.

Hope this helps someone who wants to do a cheaper better fuel pump for the sending units like this one. The Warbro 255lr/hr pump is 99.00

Here's the process.

Dis-assemble with screwdriver. Push in the two tabs on each side of the slide in plastic center section, it comes apart. Remove all old parts from inside, including the black plastic line/rubber gromits ect. Gut everything.

Put the pump back in the black rubber jacket that was on the old pump. It sets the right depth for the new one. It's snug, but it'll go on. Light oil might help slid it on.

The pump comes with all hose/clamps/wire harness adaptor. Plug and play.
I cut approx 1/4 to 1/2" off the hose it comes with since the pump is on "springs" and you have to push it down some in the tank. By cutting that small peice off it pre-loads the springs and it shouldn't kink the hose when you put it in the tank.

If you leave it too long there's a chance when you push it down into the tank it could fold too far and kink the rubber feed line, that's really it. I filed the top of the sending unit by where the wires plug in so I could get the screwdiver/clamp on a little deeper.

All apart and gutted http://www.michaelrenz.com/upload/files/255apart.JPG

This is all the stuff you won't need http://www.michaelrenz.com/upload/files/255Unusedoldpumparts.JPG

All parts... tools old/new and kit. http://www.michaelrenz.com/upload/files/255Oldnewparts.JPG

This is almost together. Need to cut that much off the hose (excess to load the springs). Then slide it all back down into the housing and make sure the fuel sock(Strainer) is at the bottom. Click the wires together and it should look like this. http://www.michaelrenz.com/upload/files/255together.JPG

You can try to re-use the plastic line attatched to the top of the sending unit. It is tough to get it off the stock fuel pump but possible. Then use a Fuel injection style hose clamp, Smooth metal clamp. The package will be labled "fuel injecton" clamps.

Note: I had a issue with 25,000mi on the fuel pump where the hose pictued below "Grew" maby with the local stations having some ethanol in the fuel. It was kinked a bit after it grew and causing some feed issues. I decided to use two small sections of hose and a peice of 3/8 steel fuel line between the pump and pipe, then pipe to top of sending unit so there was no chance of it growing and pinching off over time. I know the turbo buick's use just a small section of this hose with no failures. http://www.michaelrenz.com/upload/files/255together.JPG

Here it is all together and with the box part number for you. That is how much hose I cut off the end to pre-load the springs. Shouldn't take much longer than 15-20min to do this. http://www.michaelrenz.com/upload/files/255finished.JPG
