Never worry about leaving your gas cap behind again. This self-sealing push-through gas cap allows you to fill your tank without removing the cap—just insert the fuel nozzle through the spring-loaded door for a clean, no-mess refuel every time.

Made from durable nylon 66, the cap features a 2-5/8" outside diameter and threads into 1-49/64" filler spouts. It’s compatible with 1928-32 Ford saddle tanks, as well as many Tanks Inc. push-through cap and neck kits and fuel filler doors, and can replace various OEM screw-in caps.
