I've got an LO3 1989 Camaro RS with 305 v8, is the fuel pump inside or outside the tank and can I change it myself if its outside?? If its outside where should i start looking.

I believe that the stock pump can barely even keep up with a stock 305.

The fuel pump is in the tank.I think you have to drop the rearend and lower the tank to get the fuel pump out.

 

I dont' like that idea.

 

Hopefully i can get a definite answer out of this....but when you say "drop the rearend" are you saying to just let it hang freely or do you actually have to unbolt the shocks?

Reason I ask is because i saw some doods trying to remove a gas tank from a thirdgen and the rearend was just hanging freely. They were trying to wedge the tank between the axle and trunk/bumper and it was a very tight squeeze. I never saw if they got it out but they were having a hell of a time trying.

Welp, i just did this recently. When he said drop the rearend he meant totally. Shocks and all. If you just lower the rear the edge of the tank will just hit the houseing and tick you off even more. Then you have to wiggle and giggle the fillup "hose" out. This i found to be the hardest part as it has bends and such. It took me about 12 hours to do. With another person helping. But note that i ran into problems with the "trackbar (some call it the panhard)" So expect to run into things that don't want to come off.

With all that down time, danger (you know, GAS), and labor involved, I had a local shop do it. It cost me $130 (labor only), but if anything went wrong later, which it did, then they had to fix it free cause they did it wrong, not me. All that went wrong is one of the panhard bolts wasn't tight, and made a lot of jiggling noise. But if it would've snapped, then they would've been the ones liable, not me.

Sometimes it pays to pay.

I changed the pump in my 89rs, with out totally removing the tank, I just raised the body as high as the brake lines would allow, and dropped the axle as far as the brake lines would allow. and tilted the tank downward so the lowest point was was the right side of the car, and there was enough room for me to get in between the tank and the body, of course I removed the shocks & springs, and pulled aside the exhaust system.
It was the most PITA job I've ever done on this car. But it only cost me 60 bucks Canadian for the pump (carter), if I took it to a show they where gonna charge me 500 bucks.. I don't think so..

Sounds like a very risky method. There is a high risk in damaging the filler neck where it enters the tank if tweaked. I changed the fuel pump myself, but it is not for the faint of heart. I was swapping rear ends at the time, so perfect timing. I used a floor jack to help remove the tank. But I discovered the 3" exhaust pipe where it goes over the axle was in the way. I was SO tempted to cut off the filler neck to pull the tank. Instead I ground off the tack welds connecting the exhaust and rotated the entire exhaust system out of the way, while leaving the intermediate pipe in place. This allowed me to drop and rotate the tank to get it out. Can you do it yourself, yes. Does it sound easy? I hope not, because it isn't.
