Building a custom fuel cell or need to replace a damaged cap on your race car, hot rod, or off-road vehicle? This billet aluminum fuel cell cap is a high-quality piece. It's designed for a flush mount on 12-bolt fuel cells (and might fit other similar cells). The cap itself has a 5.5-inch outer diameter, with a 2.25-inch (57mm) opening for your filler neck. It's machined from solid aluminum and has a sleek silver finish that looks professional and tough. The best part? The kit comes complete with all the mounting hardware you see in the picture: the cap, nuts, washers, bolts, and even a cork gasket to ensure a good seal. This isn't a safety-rated part for street use; it's intended for competition or off-road vehicles where a custom fuel system is needed. Professional installation is highly recommended to make sure everything is sealed up safe and tight. If you're doing a build, this cap adds a clean, finished look to your fuel setup.
