2004 Tahoe fuel issues.

Not necessary to remove the shaft. Just stress to be careful disconnecting lines. They can get brittle and break - so just take your time. Make sure you raise the vehicle up high enough to get the tank out from underneath it.

Don't know if you have an evaporate canister it's a black rectangular box. Next to the fuel tank in the front. I've heard some don't have it. But if you do there's a hose that's connected to the fuel tank you need to disconnect it. I pulled my tank out not knowing it was hooked up and broke the Nicole off the box a 200 dollar mistake! But it really easy to do only pain was putting the tank back in a helping hand would have been welcomed. Just to put the straps back on.

I swapped my pump in about 2 hours. That's minus the 3 hours to pump the tank out with the small pump I borrowed! I backed the rear onto some ramps and lowered just the backside of the tank. It was a little tight but I got it replaced. If I could have raised it about 6inches higher it would have taken half the time. I had to pull the filler tube off the tank to get the anti siphon screen out before I could start draining. All in all it was a fairly easy job. It's been two weeks and the truck hasn't had any issues and has more power.

So I did the job Sunday. Took about 3 hrs, not counting the trip to the parts store to get a new lockring (ordered wrong one). Most time was 'figuring it out' so to speak.

I tested the fuel pressure and it holds once primed, but pressure is about the same. 42-45 psi. I have not yet changed fuel filter. I will do that after our trip this weekend. I was afraid of damaging the fuel line. In retrospect, should have done it when system was apart....

I will do a write up of my experience (mostly for myself if i ever have to do this again).

I've always thought 42-45 psi was in spec for these models, but I'm not sure.

I thought it was higher. But I could not find the FSM section on the fuel. Swear I saw it before but could not find it anywhere.
