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

The OneFastShop Dual Outlet Fuel Pump Fitting is a precision-machined adapter that mounts directly onto your Walbro fuel pump's outlet stub. It splits a single pump outlet into two 7.89mm SAE male quick-connect ports - both of which mate 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.

How It's Used

This fitting works in two distinct configurations:

• Single-pump splitter: One pump's output feeds both 7.89mm ports - useful for dual-feed lines, parallel fuel rails, or high-flow setups where you want to split flow from a single pump into two paths.
• Dual-pump combiner: The fitting mounts on Pump A. Pump B's output line connects into one of the 7.89mm ports. Both pumps' flow combines through the fitting and feeds out the remaining port to your car. The classic configuration for dual in-tank pump setups on high-power applications.
