    Product Description

    High flow brass fuel line fittings.  These are the same brass fittings available in our full fuel line kit.  Available for purchase for anyone wanting to use their own fuel line and clamps.  You get one pair of machined brass fittings.   
    Fully machined brass fittings combined with your quality Tygon fuel line allow for unrestricted fuel flow. Bring your engine back to life and get rid of those stock restrictive fuel lines!  The barbs are integrated into the fittings and they hold super tight in the rubber grommet. You get a full unrestricted fuel flow with 0.125" ID from the tank to the carburetor.

    The stock setup on most 5th scale trucks creates a restriction where the fuel lines enter the tank through the rubber grommet.  This is the fix for this common issue.

    • Fits the HPI Baja series, Losi 5ive-T,  Kraken Vekta, and many other 5th scale trucks. 

    • Can be made to fit the Losi Desert Buggy XL by using the "fuel line trick" but getting the stock grommet to fit back in the tank can be a little tricky.  Patience is required.

    This is the "Original" 2nd Generation High Flow Fuel line kit made by us here at FFRC.  We make this stuff all in the USA with quality material.  Do not accept any imitations made overseas by people who can't originate an idea.  We've been told that there is now more than one knockoff version of our product out there.  Sorry but we do not offer any support for other peoples poor copies.

      Buy these!

      Posted by Brian Holden on 9th Jun 2026

      I have these on all my gassers now. This is a better deal than buying their kit. Its a little cheaper and you use your own fuel line as they only supply the yellow tigon brand stuff in the full kit. These things really clean up the routing of the lines and look a lot nicer. FFRC is my place for these things and more. Always super fast shipping and no concerns.

      Best upgrade

      Posted by Daniel Moss on 3rd Jun 2026

      This was the best little upgrade in my order. It routes the fuel lines a lot nicer and looks great. Did not notice any difference in performance but I can see how the fuel lines could get pinched over time. My truck was pretty new when I installed these and I just really like the looks more than anything.

      Excellent quality. Barbs on ends hold fuel line nicely and fit snuggly in fuel tank grommet.
