OH MY GOD. I am a guy that does most repairs myself, but this one clearly was the repair from hell. Note that the cost was $600, because I did it myself. Had I paid someone else to do it, it would have cost twice as much. In order to replace the fuel pump on these trucks, you must DROP THE GAS TANK, while simultaneously being careful enough not to break the little evap valve on the top front side of the tank, which is nearly impossible, thus causing you to pay an additional $30 for this small cheap plastic piece that is only available at GM stealerships. I'm sure they designed it that way on purpose.

My gas tank was only half full when we dropped it, but here's a word of advice: Drive it until nearly all the gas is gone, unless you can afford an expensive siphoning device. Gas weighs a boatload more than water of the same volume, so you must keep that in mind. Even two strong guys can have trouble with this one, as we did. If the pump fails again, I'm paying someone else to do it. TRULY.

But what really pisses me off is that GM placed the damn thing in the fuel tank in the first place. Why not put it on the fuel rail, where it's a lot easier to get to? Makes too much sense, I guess. Another option would be to place it near the rear of the tank, in such a way that makes it unnecessary to remove the tank to remove the pump. It could be done, but some dips***t at GM didn't think it was that important. It's so obvious they are trying to fleece you later with repair work.
