Goinghuntin Posted August 23, 2010 Report Share Posted August 23, 2010 I had to replace the fuel pump and sending unit in my truck this weekend. Well yesterday I went to fill the tank up and gas started pouring out the top of the tank. Apparently the large o-ring either fell out, cause I know I put it on before tapping the lockring in place, or it got all crooked. Either way I'm going to have the drop the tank again and check it out :bang: Seems I can't catch a break lately. Nathan Quote Link to comment Share on other sites More sharing options...
Jeramie Posted August 23, 2010 Report Share Posted August 23, 2010 And you have to drop the tank full! That stinks..... One thought, would you have easier access if you pull the bed off? Quote Link to comment Share on other sites More sharing options...
92xj Posted August 23, 2010 Report Share Posted August 23, 2010 Pull the wiring harness off the rear lights and trailer hitch. Pull 6-8 bed bolts and the filler neck of the gas tank and pick bed up and slide back. I am assuming this is a chevy/gmc truck. 99% of the fuel pumps that ever need replacing are on them. I have never once dropped a tank with a gmc/chevy that has a bed after 6 years working at the shop. Quote Link to comment Share on other sites More sharing options...
Goinghuntin Posted August 23, 2010 Author Report Share Posted August 23, 2010 One thought, would you have easier access if you pull the bed off? A few years ago we had a fuel pump go out in my Dad's '88 Chevy work truck. We ended up cutting a hole in the pickup box right above the pump to pull it out. One the best ideas I've ever had But not with this one, I drive a Jimmy :helpsmilie: It's not hard getting the tank down and back in it's just very time-consuming, and I have to work all week and half of the weekend.

Shaun_300 Posted August 24, 2010 Report Share Posted August 24, 2010 Make sure you put lots of brake lubricant (clear silicone type) on the seal. That's probably what happened. As soon as you go to tighten the lock ring it'll tilt out of place and give you a leak. Quote Link to comment Share on other sites More sharing options...
