Walbro 450 525 535 Hellcat Single Outlet Fuel Fitting - 7.89mm QC

The OneFastShop Single Outlet Fuel Pump Fitting is a precision-machined adapter that converts the barbed outlet of your Walbro fuel pump into a 7.89mm (5/16") SAE male quick-connect port - mating directly into factory-style 7.89mm female quick-connect fuel hardlines. No pump modification, no hose clamps, no adapters.

The fitting slips over the pump's barbed outlet and is secured with a locking ring. An internal Viton O-ring creates a leak-proof seal compatible with gasoline, ethanol (E85), and all common race fuels. Fully reusable across multiple installations.
