i did it and have had no problems or issues. here is a write up. i cut my hole further back towards the back of the car. just be careful not to cut down to far.

I have never experienced that but,.... Wouldn't it be better to just drop the tank as opposed to cutting up the car?

^^^What he said, use a little RTV and you should be good to go.

Ya i just took the panel i put back on and put a 1/4 bead of rtv all the way around. then before i put it on the car, i let it dry so it formed a "seal" then just screwed it on. No fumes, no problems.

Here's my pics ... it's on a '98 T/A, follow this and you'll be happy ... lol

Just remember, the 98's have a different location than the 99-02's for the fuel pump door, so make sure you get the ones for a 98.

i consider this correcting an engineering oversight. all these gm vehicles need fuel pumps, some sooner than later and there should be no reason to have to put a car up in the air and undo, move, or remove all the stuff you have to just to replace a fuel pump. pickups at work are the same but a lot grungier underneath. unless you have a 10 point trailer/ garage queen i dont see what harm it can possibly do.

From the pictures posted it seems convenient to change if it will be changed frequently. I'm not saying it will harm anything from cutting but i think I would rather not cut it. Unless its going to have to be changed every year, then I might consider it.
I agree and consider it an engineering oversight. I also think they did it on purpose so the car would return to the Chevy house for repair.

I did it on mine just as above I even did the racetronix fuel pump because my housing was still good. It came out to be $150 instead of $400 for a whole new pump. Did it a few months ago and havent looked back its completely quiet and no one is none the wiser.

I did this on my 93 T/A and never had a problem....when my 00 WS6 needs a fuel pump I'll do the same thing.

did it with my 89 and had a problem with fumes but once you seal it up you won't have a smell

**allbaugh_04** · 05-20-2009, 06:55 AM

I'll have to remember this incase mine ever goes bad.

you have to seal it up, otherwise you will smell exhaust fumes and maybe a little gas. but i guess you know that now.

That's a nice hole you cut! You think it would be O.K. if I use my PLASMA cutter?

JUST KIDDING! What tool did you use to get such a nice clean cut?

**SS SLP2** · 05-21-2009, 06:33 AM

no problem after 2 years, operation easy, I used a durmeral (sp )grinder.

one safety point, let some slack in the straps which hold up the tank so as to have a little clearance over the top of the fuel lines when cutting the hole
