Replace 92 GMC fullsize truck fuel pump: Cutting access panel

I recently had to replace the fuel pump on my 92 GMC Yukon. 2 years ago I replaced the fuel tank, and it was truly a miserable job. Yeah, should have replaced the pump then!

Newer vehicles sometimes have a access panel in the rear floor so the pump can be replaced without dropping the fuel tank. I decided I wanted one, so I carefully sized and cut a rectangular section out, replaced the pump and reconstructed the floor as a panel I could open again if really needed..

Pictures are better than words for this, so if you're interested, take a look at:

OTHER DATA: A new pump has a resistance of 11 Ohms. The 'bad' pump, with 140,000 miles on it, had a resistance of 60 to 70 ohms (probably worn-out brushes).. Perhaps an occasional checkup on your older truck would include measuring the pump resistance. I think this pump was slowly dying for a while... I had a funny light-throttle surging problem that went away with the new pump..

Thanks for the help I've gotten in the past here and across he Net!

good job. here's a more elegant idea for you though - why not just go to a junkyard, find a similar truck, and cut a larger piece out of the floor. then cut it down to maybe 1-2" longer in each direction than the hole you made, screw it to the floor with sheet metal screws.

Good idea, Nate!

... Although I am deeply hurt by the idea that a truck "just like mine" could be found in a Junkyard :-)

Just saw a 2008 in a yard yesterday. Had what looked like minor damage to the nose but it had been totaled out. (to expensive to repair)

I like it too. But I'm not taking a fuel tank pump out to check it. If it comes out its getting replaced.

I just did my 89 S-10 pickup. A gigantic pain. If I had it to do over again I would remove the bed.
