Description
When a fuel cap fails, the fix should be simple: match the spec, thread it on, done. The FC1349AD is built for exactly that — a 3.00-inch diameter, 8 TPI female thread that matches standard diesel fuel tank openings, so there’s no guesswork or extra hardware involved in the swap.
The aluminum body is what makes it worth ordering over a generic steel replacement: it resists corrosion and won’t seize onto the tank neck the way rusted steel threads do, and it’s noticeably lighter to handle during install. Non-locking and non-vented, it’s a straightforward replacement for fuel systems that don’t call for a keyed cap or cap-level venting.
