Fuel pump and level sender removal; what ring?
I'm trying to remove my fuel pump and level senders but everything is covered in rust (surface, nothing goes through) and I can't get the rings on the senders to break loose. Not sure if I'm hitting the right one though. There is an inner ring with 3-4 small raised tabs (1/2" long) and an outer ring that is the opposite (raised ring with 3-4 1/2" openings in it where you can hit it to loosen). Which one? and yes, i've got a bunch of PB on them.
