Description

Fit precision is everything with a fuel cap — the diameter and thread pitch have to match exactly, or it won’t seal. The FC01683 is a 2.00-inch diameter cap with an 11.25 TPI female thread, noticeably finer than the 8 TPI pitch used on Cleveland Tank’s larger 3″ and 4″ caps. Getting that thread count right is what keeps the seal tight, so confirm your tank’s spec before ordering — a mismatched pitch won’t thread on correctly even if the diameter looks close.

The body is machined from lightweight, corrosion-resistant aluminum, so it holds up to years of outdoor service without rusting or seizing the way a steel cap can. It’s non-locking and non-vented, a straightforward, no-frills replacement for fuel systems that don’t call for a keyed cap.

    Diesel Fuel Cap –

    The FC1010 from Cleveland Tank is a vented brass diesel fuel cap with a male thread design, for fuel tank necks that take a male-threaded cap rather than the female style used on most of Cleveland Tank’s other caps. It has a 2.125-inch diameter and 12 threads per inch (12 TPI), non-locking, and vented so the tank can properly equalize pressure as fuel is drawn down instead of risking vacuum lock. Brass construction adds durability and rigidity over a standard aluminum cap. At 1.0 lb and 2.125 x 2.125 x 2.0 inches, the FC1010 is a direct-fit replacement for diesel fuel systems specifying a 2.125-inch, male 12 TPI vented brass cap.

  • Brass Non-Locking <br/> Diesel Fuel Cap - <br/> 2.00" Diameter

    Brass Non-Locking
    Diesel Fuel Cap –
    2.00″ Diameter

    The FC1008 from Cleveland Tank is a vented brass diesel fuel cap 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 2.00-inch diameter and female threads at 11.5 threads per inch (11.5 TPI), non-locking, built from brass for extra rigidity and durability over a standard aluminum cap. Fitting a non-vented cap on this type of system risks vacuum lock, so the FC1008 is specced to avoid that while still resisting leaks, cracks, and contamination. At 1.0 lb and 2.0 x 2.0 x 2.0 inches, it’s a direct-fit replacement for diesel fuel systems specifying a 2.00-inch, 11.5 TPI vented brass cap.

    The FC1015 from Cleveland Tank is a brass locking diesel fuel cap with a male thread design, for fuel tank necks that take a male-threaded cap rather than the female style used on most of Cleveland Tank’s other caps. It has a 2.125-inch diameter and 12 threads per inch (12 TPI), and it’s both locking — deterring fuel theft and tampering — and vented, so the tank can equalize pressure properly as fuel is drawn down instead of risking vacuum lock. Brass construction gives it more heft and durability than Cleveland Tank’s standard aluminum caps. At 1.0 lb and 2.125 x 2.125 x 2.0 inches, the FC1015 is a direct-fit replacement for diesel fuel systems specifying a 2.125-inch, male 12 TPI locking vented cap.

    The FC1012 from Cleveland Tank is a brass locking diesel fuel cap, built from a heavier, more rigid material than Cleveland Tank’s standard aluminum caps for applications where extra durability matters. It has a 2.00-inch diameter and female threads at 11.5 threads per inch (11.5 TPI), and it’s both locking and vented — the integrated lock secures the tank against theft and tampering while the vented design lets the tank equalize pressure properly as fuel is drawn down. Two keys ship with every cap. At 1.0 lb and 2.0 x 2.0 x 2.0 inches, the FC1012 is a direct-fit replacement for diesel fuel systems specifying a 2.00-inch, 11.5 TPI brass locking vented cap.
