Thread: Gas filler cap won't open......

    Gas filler cap won't open......

    An owner just had his gas cap stick shut. Here is a review of his fix, and some illustrations of the cap and it's mechanism in case it happens to you.

    I made a 3/4 scale plastic toungue depresser device and was able to sneak it past the gas door lid (blue-taped for scratch prevention) and the quarterpanel opening. After some careful wiggling into the lock latch it opened. I wouldn't worry about someone stealing gas, as it is a real pain to get by the boss above the latch.

    The cable #16 from the motor #17 to the lock #15 broke came off where it joins the gas cap latch. It wasn't the metal cable, but a super flimsy nylon fitting that attaches to the cable and fits into the latch. This piece was added prior to the cable ends being swagged onto the strands.

    Replacement requires the removal of the wheel, inner fenderwell, and the right side trunk liner.

    Tools; 10mm socket and a couple of torques bits and about an hour or so of puttzing.

    The lesson is, if the cap doesn't open, and the emergency lever doesn't release, then take off the wheel and inner fender and you will have access to the cap lock.

    Same issue here. The photos were hugely helpful. I used a small plastic spatula inserted to access where the metal clip meets the actuator in the second photo and it did the trick. Thanks for the great post.

    Is this about the cap refusing to unscrew or the door failing to pop open?

    My door works, my cap has siezed in the filler tube twice, requiring destruction of the cap to get it out.
