Description

The FC01404’s integrated lock keeps fuel secured against theft and tampering, and it ships with two keys included, so there’s already a spare on hand instead of a scramble if one goes missing. It’s also sized larger than Cleveland Tank’s standard fuel caps — a 4.00-inch diameter fitting instead of 3.00 inches — with the same female thread pitch (8 TPI) as the smaller locking caps, so it’s a direct-fit replacement where a larger neck size is spec’d. The lightweight aluminum body resists corrosion far better than a steel cap.

Non-vented, this cap is built for fuel systems that vent through a separate equalizer line rather than through the cap itself — confirm your tank’s venting setup before ordering.
