Fill Line Kit

The ALLSTAR PERFORMANCE Fill Line Kit (ALL 36148) is purpose-built for serious fuel cell installations and high-performance racing applications where precise fuel delivery lines must be routed cleanly and reliably. Whether you're retrofitting a custom fuel cell into a street rod, competition drag car, or weekend warrior, this kit eliminates the guesswork of sourcing individual hose segments and fittings. Mechanics and fabricators trust Allstar Performance components for their consistency, durability, and seamless integration into OEM and custom fuel systems.

This fill line kit ships complete with 3 feet of 10 AN braided hose, a straight 10 AN fitting, and a 90-degree 10 AN to 1/2 inch NPT adapter, giving you the flexibility to plumb fuel cells in tight engine bays or unconventional layouts. The 10 AN (AN10) hose standard is industry-standard for fuel systems up to moderate flow rates, offering excellent pressure rating and abrasion resistance under vibration. The combination of straight and 90-degree fittings allows you to route fuel lines around engine components, frame rails, and suspension elements without kinks or stress concentrations that could compromise line integrity over thousands of heat cycles.

Installers of custom fuel cells, fuel-injected restorations, and race cars benefit most from this kit's pre-matched components and premium hose quality. The 1/2 inch NPT adapter end connects directly to most aftermarket fuel cell filler necks and vent ports, while the 10 AN end integrates seamlessly with fuel pump assemblies, surge tanks, and distribution blocks. Installation requires basic AN hose fitting knowledge and standard automotive hand tools; the kit's compact footprint (7.7 x 2 x 8 inches, 0.98 lbs) makes it portable for shop or track work. Verify your fuel cell's inlet and vent port sizes before ordering to ensure this configuration matches your plumbing scheme.
