I'm making 540rwhp on the stock fuel lines. I should crack 600 this spring with dual fuel pumps and every one I have talked to has said I should be good to about 650rwhp before I have to add bigger lines and fuel rail.

I pulled the exhaust off the Y pipe. Then I unbolt the panhard rod, shocks, and sway bar from the rear. Leave the drive shaft, torque arm and lower control arms on the rear. Then slowly let the rear swing down out of the way, watch the E brake cables and brake lines, when they are starting to get tight I will stop and raise the rear just a bit to take the stress off the brake lines, and cables. Open the gas fill door and take out the 2 or 3 screws holding the black plastic around the fill neck. Then get in to the wheel well... between the tire and rear bumper. There is 1 bolt holding the fill neck to the car, remove it. Also I will drive my car around untill the check gauge light comes on so the tank is as light as possibe. Next remove the 2 straps holding the tank in the car, let it down on the axle, remove the fuel lines and electric plugs and the the tank can come out on the floor.

I just cut the trap door and installed a racetronix in mine this week. I have true duals so the exhaust wasn't even an issue. unfortunately with aftermarket pumps they are hit or miss and have a reputation of commonly go out. I can do a pump swap in under 30min now.that will prove to be a good thing it craps out at the track, side of the road, etc...

to the OP, in my old car I put down 575/611 to the wheels on a regular ol' walbro 255. that car didnt even have the "hot wire" kit.
