Our super-clean pop-up gas caps can be welded into almost any aftermarket gas tank. When installed and painted, these caps are perfectly flush with the tank surface and are almost invisible. To access the filler bung just press and twist and they will pop-up, then uscrew normally.
Bungs have a 2.32″ (59mm) outer diameter, caps are 2.16″ (55mm) in diameter.
