I'm tying to change my fuel pump in a 99 Reg Cab and ran into a few problems. We already took off the bed for easier access so thats out of the way. Anyways do I spin the ring to what looks like the free position? Second the metal ring around the fuel pump is rusted through almost, has anyone encountered this? Third, how did you take off your fuel fittings, I have a tool from autozone but it doesn't fit. Any advice would be great.
