• Vented Filler Cap with Check Valve and Steel Weld In Bung


    Vented aluminum filler cap with steel weld in bung. Stainless Steel ball inside of cap blocks the vent if vehicle flips to help prevent liquids escaping.

    The cap is not designed to be used in rough environments such as boats or other vehicles that may cause fuel to splash out of the vent. Install and use at your own risk.

    Threads are 1 1/4 - 12

    Cap OD is 1 3/4"

    Bung drop through diameter is 1.5"

    Viton O Ring included

    Made in the USA

    If you need the bung and cap to sit higher on your tank, choose the added height you need from the drop down menu. I will TIG weld a chromoly 4130 16 ga tube to the bung. The added tube will be measured from the bottom of the mounting lip on the bung.
