    All engines

Intended for compatible 1986–1995 Ford Mustang 5.0L V8 applications. Verify exact model year and EFI configuration. Confirm whether the vehicle uses a return-style or modified fuel system. Check fuel tank and pump arrangement. Verify feed and return line sizes. Confirm fuel rail and regulator configuration. Check injector flow requirements and horsepower goals. Naturally aspirated and forced-induction setups may require different pump and regulator capacity. Aftermarket fuel rails may require specific fittings. Engine swaps can significantly change routing and connection requirements. Ethanol-blended or alternative fuels may require compatible hose, seals, pump, and regulator materials. Verify electrical requirements for high-flow fuel pumps. Fuel pressure should be tested after installation. All fittings and hose connections should be checked carefully for leaks before driving.
