    FAQ

    What carburetors does this fuel line fit?

    It's designed for Holley 4500HP Dominator carburetors using Gen 3 -8 O-ring HP fuel bowls.

    Why is this line longer than the standard fuel line?

    Gen 3 HP bowls hold more fuel, which adds .125" of length per bowl, so this line measures 11.5" versus the standard 11.25" line.

    What material and finish does the fuel line use?

    It's built from black anodized aluminum billet for corrosion resistance and a clean, durable finish.

    What size AN fittings are used?

    The line uses -8 AN fittings on both the dual inlet and outlet.
