    OE Quality for the Aftermarket

    Our long-standing partnerships working with automotive OEMs on production vehicles enable us to produce aftermarket parts of superior quality, durability, and performance. OEM-caliber fuel caps are rich in features that keep the fuel system operating properly and safely. The Green color reminds motorists that the vehicle is only compatible with diesel fuel. Gates® Diesel Fuel Caps offer a durable construction of a wear-resistant thermoplastic compound to ensure tight closing and to avoid spills and leaks.

    Optimum fuel pressure

    Fuel caps can have two different breathing systems: vented or non-vented. A non-vented fuel cap is recommended when your fuel tank is ventilated through the filler neck, whereas the vented fuel cap is equipped with a special breathing valve so that it can be used on non-ventilated fuel tanks.
