The OneFastShop Single Outlet Fuel Pump Fitting is a precision-machined adapter that mounts directly onto your Walbro fuel pump's outlet stub. It converts the pump outlet into a 7.89mm SAE male quick-connect port that mates directly into factory-style 7.89mm female quick-connect fuel hardlines. No hose clamps, no adapters, no permanent modifications.
The fitting slips over the pump outlet and is secured with a tightening collar. 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.
Designed for the Walbro / TI Automotive 39/50 DCSS pump family. These pumps share the same external dimensions, outlet stub design, and install pattern:
