Not quite that easy. I believe a 75 would be the same as my 77. First, remove as much gas from the tank as possible. Then drop the spare tire and the housing. Then drop the exhaust because the mufflers are in the way. Then drop the tank partially, then you can reach the hoses. Then drop tank out. There is a large metal enclosure above the tank that had to be removed to finish the fuel line work.

did you check the "S" hose that hooks up to the fuel pump from the fuel line they sometimes will kink whent they warm up. make sure that it is the molded hose and not a piece of fuel line, which will kink, ask me how I know.

Good advise.

So a few weeks ago I dropped the tank and checked the sock. Completely brand new sock, so that wasn't the issue. I then started to have the same sputtering/lean gas situations at 1500 RPM and a very rough idle, so taking everyone's advice figured I needed to change the fuel pump.This weekend I changed the fuel pump. That was the issue. Completely different beast now. Revs up much faster, has tons of power, and really completely transformed the car. Thanks everyone!

IMHO; I hope you put the new sock on any way, so as to not waste your labor in doping the tank, then all components are new, then all will be good for many years!!!

That was the process but mine has a custom exhaust. It goes so far out that I didn't need to remove any of it to remove the tank. Just unscrewed it, twisted it and it came right now. Thanks!
