MK4 gas cap

[Mark Eaton]

Does anybody happen to know the part number for a replacement fuel cap for an MK4?

This is the one I bought:

I think any of the "Push & Lock" type caps will work.

That one won't work with the MK4, at least not with the La Mans parts that my kit came with.

Ah, thanks for letting me know! I picked one up but hadn't had a chance to install it yet. Looked like a nice design. Bummer that it won't fit. I guess I put it up in the classifieds.

Just to save some frustration, in Jeff's pic the screw in the middle of the bottom of the Le Man's cap will loosen and fall out.
Tightening down is not an option, as the lid assemble is spring loaded.
Remove the screw, which is under spring pressure. Put blue loctite on the threads and install with enough spring tension to make the Le mans lid close and open under tension.

I got a locking gas cap - Motorcraft- FC1005 Fuel Cap - you need to rotate the Ford symbol out of the way to close the Lemans cap. I took the strap off because I didn't want it hanging down on the rear fender.

I got the locking one for added security as well as the fact that I can't forget it at the gas station! The key for the gas cap is on the same key ring as the Roadster ignition, and I can't take the key out without locking the gas cap!!
