TANK WILL HAVE TO BE DROPPED. TAKES ABOUT 5 HOURS FOR TOTAL JOB. NOT EASY.

Not like the old days of replacing a fuel pump on a 350. :-(

Nope them days is gone. I have actually seen that fuel pump replaced on the ground in about 45 minutes(not even on a lift). If you have never done one before it will take about 5 hours. You must push the filler neck out of the truck so you can disconnect from the tank. Have tank as empty as possible, put truck on jack stands and lower the tank down with a jack. Snap ring on top of tank comes off, remove old pump assembly, put vaseline on new o ring and re-install.

* 2000-2002 1500's have a re-call on that pump. The parts will be available in November. If you have replaced one already GM will reimburse.

Do they reimburse for the labor and parts?

As long as you have a receipt for both you should be fine

Bit late on a response to this, for if you have the problem, you need to address it pronto. I've had two go out on my 96. $400 sounds right. First one was under warranty, the second, about 3000 miles past warranty.

I now change the fuel filter every other oil change.

Would like to know if anyone has retro fitted to eliminate the in tank pump. Not a great design for a 4by. I know not many people really use theirs off-road, but for those of us that bought it to use it, a trail changable fuel pump would be nice.

I have heard about the fuel pumps going on on mid-late 90's on this engine. Is it true that if you never let your fuel tank drop under a 1/4 of a tank, that this will keep the fuel pump from messing up? TRUE/FALSE?
If you need to buy a new fuel pump I would get it here www.gmpartsclub.com

rbruce............I think you could safely put an electric fuel pump midline for a back up. Just make sure you have the fuel pressure regulated correctly. The fuel guage may or may not work either, but offroad who cares.

apache.....when your tank gets below 1/4 full your fuel pump will become pretty noisy. Keeping that fuel pump completely submersed (1/4 to 1/2 full) is certainly better for it, but may not guarantee it won't fail.
