Description

Some fuel systems just need a dependable, correctly sized cap — no lock, no extra hardware, just a tight seal. The FC01015 is built for that: a 2.125-inch diameter cap with an 8 TPI female thread, the same thread pitch Cleveland Tank uses on its larger 3″ and 4″ locking caps, so fitment logic carries over even though this one’s smaller and non-locking.

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-vented as well, a simple, no-frills replacement for fuel systems that don’t require a keyed or vented cap.

    Diesel Fuel Cap –
    2.00″ Diameter

    The FC1009 from Cleveland Tank is a brass diesel fuel cap for fuel systems that need the added durability of brass without a locking mechanism. It has a 2.00-inch diameter and female threads at 11.5 threads per inch (11.5 TPI), non-locking and non-vented, built to resist leaks, cracks, and fuel contamination. Brass construction gives it more heft and rigidity than a standard aluminum cap, holding up well to repeated fueling cycles and rough handling. At 1.0 lb and 2.0 x 2.0 x 2.0 inches, the FC1009 is a direct-fit replacement for diesel fuel systems specifying a 2.00-inch, 11.5 TPI female-thread 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.

    Brass Locking
    Diesel Fuel Cap –
    2.00″ Diameter

    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.
