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
