Hello, I have a 79 Euro that was French delivered, 79 chassis 0057. The gas cap it came with is a sawed off plastic one, I assumed that was because the key had been lost by the PO.
However I just bought a red plastic cap from ebay (the one in the picture) and when screwed on it protrudes from the car so that the gas cap door will not shut flush.
Do I have a quirky factory variant that had a metal cap a la 78, or am I missing something?
6 in Germany - I ordered one for my interesting parts collection

928 Owners are ".....a secret sect of quietly assured Porsche pragmatists who in near anonymity appreciate the prodigious, easy going prowess of the 928."
I have one here off of a '79 but it's as hard as a rock- like a solid chunk of plastic. Will be interested to see if the NOS ones are still pliable. They sort of grasp onto the flange in the body sheet metal there.

If you can measure it, it could likely be duplicated in a new material.
Either by way of 3d printing with a flexible plastic, or by carving out a replacement from a block of a suitable material.
I'm going to be taking a look at the tank on my car, since the filler neck is awfully close to the top of the gas door opening.

And does anyone want to buy a red 928 gas cap?
when the gas door won’t close it’s usually because the tank is crooked in the cradle. It only takes a few mms of mis alignment on the bottom to tilt the tank out at the filler cap area. Ask me how I know. You can loosen the cradle bolts and adjust it around a little.. it has to be in the right place, at the right angle, with the right rotation for the gas cap and bellows and gas door to fit right. The earlier tanks and cradles seem to be harder to get in the right place than the later LH type..at least they are for me. The 78 metal gas caps don’t screw on to later tank threads very well either ...slightly different threads. It is possible that 79 euro #57 May have had a metal cap though. When you pull your cradle down you can see the date stamp on your tank.
Not much else to add other than a thick piece of rubber or neoprene works well in lieu of the P-part.
Also a spacer on the tank filler 'snout' strap helps to not over-tighten the strap and stress the snout.
And what Droo said about adjusting the cradle, very important.
Re gas caps, there's no definitive proof of when the change occurred, other than we know it was near the end of MY78. I had '78 RoW s/n 2384 (near of of MY78 production) which had a plastic gas cap.
