Description

Some fuel tanks vent through the cap instead of a separate equalizer line, and a non-vented cap on one of those systems causes real problems — fuel flow slows or stalls as the tank struggles to equalize pressure. The FC1005 is built specifically to avoid that: a vented brass cap at 4.00 inches diameter with an 8 TPI female thread, giving you the same fitment as Cleveland Tank’s aluminum vented cap in this size, but in brass for extra durability.

Brass adds rigidity and weight that a standard aluminum cap doesn’t have, holding up well to repeated fueling cycles and rough handling. It’s non-locking, a straightforward option for fuel systems that need proper venting but don’t require a keyed closure.

    The FC1002 from Cleveland Tank is a brass diesel fuel cap with a male thread design, sized at 4.25 inches in diameter — larger than Cleveland Tank’s standard 3″ and 4″ caps. It has 8 threads per inch (8 TPI), non-locking and non-vented, and is built from brass for extra rigidity and durability over a standard aluminum cap. The male thread means it fits a female-threaded tank neck, the opposite of most caps in the lineup, so confirm thread gender before ordering. At 1.0 lb and 4.25 x 4.25 x 2.0 inches, the FC1002 is a direct-fit replacement for diesel fuel systems specifying a 4.25-inch, male 8 TPI brass cap.

    Diesel Fuel Cap –
    4.00″ Diameter

    The FC01015VNT from Cleveland Tank is a vented, non-locking diesel fuel cap built for fuel systems that rely on the cap itself — not a separate equalizer line — to let air into the tank as fuel is drawn down. It has a 4.00-inch diameter and female threads at 8 threads per inch (8 TPI), machined from lightweight, corrosion-resistant aluminum. Fitting a non-vented cap on this type of system risks vacuum lock, so the FC01015VNT is specced to avoid that while keeping the tank sealed against leaks and contamination. It weighs 1.0 lb at 4.0 x 4.0 x 2.0 inches and installs as a direct-fit replacement for diesel fuel tanks specifying a 4.00-inch, 8 TPI vented cap.

    The FC-C-92 from Cleveland Tank is a 4.00-inch diesel fuel cap with a male thread design, for fuel tank necks that take a male-threaded cap rather than the female-threaded style used on most of Cleveland Tank’s other caps. It has 8 threads per inch (8 TPI) and is machined from lightweight, corrosion-resistant aluminum, non-locking and non-vented. Weighing 1.0 lb at 3.0 x 3.0 x 2.0 inches, the FC-C-92 is a direct-fit replacement for diesel fuel systems specifying a 4.00-inch, male 8 TPI thread cap — confirm your tank’s thread gender before ordering, since male and female caps aren’t interchangeable.

    The FC01404 from Cleveland Tank is a 4.00-inch locking diesel fuel cap for fuel systems that need a larger-diameter cap than the standard 3.00-inch size. Machined from lightweight, corrosion-resistant aluminum, it has female threads at 8 threads per inch (8 TPI) and a non-vented, locking design that ships with two keys included. The lock deters fuel theft and tampering, while the aluminum body resists the rust and pitting that shorten the life of a steel cap. At 1.0 lb and 4.0 x 4.0 x 2.0 inches, the FC01404 is a direct-fit replacement for diesel fuel tanks and fuel systems specifying a 4.00-inch, 8 TPI female-thread fitting.
