Re: fuel pump

its been my understanding you have to drop the rear axel and exhaust? no?

Re: fuel pump
yeah you have to drop the rear end and remove the exhaust from the cat back. i have the same problem with mine right now. the only thing i can't figure out is how to siphone the gas from the tank. i seem to be running in to something in the tank. the tank is full and i can't even touch any fuel.

Re: fuel pump
try to pull the filler neck off at the tank and soo if you can slip your siphon in there. if that doesnt work just get help and or a transmission jack and pull it with a full tank.

Re: fuel pump
yeah i cut the exhaust and tried to drop the tank to no avail because i thought i had like a quarter tank an it was more like 3/4 so i put it back together and cut a hole. turns out the pump wasnt the problem anyways, thanks for the help guys
