The Inline Fuel Pump Fitting M10 x 1 to 9mm Barb is a precision adapter engineered for high-flow fuel system modifications and performance fuel pump installations. This fitting bridges the gap between metric M10 threaded ports and barbed hose connections, making it essential for carburetor conversions, fuel cell plumbing, and custom fuel delivery systems on street rods, race cars, and engine swaps. Whether you're upgrading from a factory mechanical pump to an electric unit or building a standalone fuel system, this adapter ensures leak-free connections and reliable pressure delivery at critical fuel line junctions.
Manufactured by Walbro/TI Automotive—the industry standard for fuel system components—this fitting features precise M10 x 1 metric thread engagement that seats flush against fuel block ports and pump outlets without cross-threading or galling. The 9mm barb design accommodates standard fuel hose tubing, providing positive grip and vibration resistance on the hose end while maintaining consistent fuel flow rates. The compact form factor and lightweight construction (0.05 lbs) minimize installation complexity, and the proven Walbro engineering ensures compatibility with both gasoline and alternative fuel applications across a wide pressure envelope typical of aftermarket fuel systems.
Mechanics and fabricators restoring vintage vehicles or building race-spec fuel systems rely on this fitting when transitioning from factory rubber line connections to robust hose and clamp plumbing. It's equally valuable for fuel system diagnostics—allowing easy disconnect and isolation of pump circuits for flow testing without permanent modifications. Installation requires only basic hand tools and Teflon tape or fuel-grade sealant; the barb accommodates standard SAE fuel hose crimpers for professional-grade terminations. Verify your fuel block or pump casting features an M10 x 1 port before ordering, and confirm hose ID matches the 9mm barb specification for optimal sealing and durability.
