Odd thing.. I just replaced my gas tank and I believe it came out of a 87. Did the seals, added a MKIV Denso fuel pump.. cleaned it all up and pressure tested it. Can finally hold a full tank of fuel.. lol

QUESTION is.. the gasket at the top of the fuel tube (plastic piece with a rubber seal that I thought was supposed to wrap tight around the fill spout) has a gap of about 1/2 inch at the top of the tube (you can put your finger in between).

I thought the fuel spouts for all MKIII's were the same diameter. Wondering whats going on? Anyone know?
