Need some help. Trying to remove the deck mouted fuel filler cap so I can slide the tank back to remove the old steering cable and wiring harness on a '78 Sunkisst. It has side mounted tanks. I have drilled the rivets holding the fuel filler cap but can't get it to pull up. There is no way to get your hand under the deck and on top of the tank so I don't think there is a hose and clamp.
Any suggestions as to what to do?
