Are you absoultely sure it's the pump? The correct way is to drop the tank, but you can also cut an access panel on the rear deck to get to it - then patch it.

no im not positive but the pump is running at 48psi or lpm whatever they rate it at, and im told and they told me that its suppose to be at 55-60

Yeah, should be about 58. Have you tried replacing the fuel filter? Pressure regulator OK? Just thinking check everything before going through replacing it. I know two people that went the access panel method, beware if you find a link on how to do it the measurements are a little different on the '98 model because the tank is different.

Drop tank.
Pump should have instructions from there.

Upgrading?? Racetronix has a solid kit that can support a lot of power, and works GREAT with stock and near stock set-ups. Better than the stocker since it gets a constant voltage.

Its suppose to run at 55-60 psi

Theres a link to gain acess from the hatch.
I also have instructions to do it the "correct" way if ya want.

its tough without a lift.get the back of the car as high as you can get it. remove the lower shock mounts(make sure you have a floor jack under the axle) lower the axle,move the exhaust out of the way then lower the tank

I did it on my 2000 camaro the other day and you have to do all that and you may have to remove the pan hard bar and brace to slide it out...not sure on a TA

yep, panhard bar and brace will have to come out. You'll also have to watch the brake lines and make sure you don't stretch those to much. They mount on the drivers side. You can take the bolt out of that bracket and that'll give you a little more length on the brake lines.
