Universal EFI Fuel Pump 43gph @ 85psi

The Universal EFI Fuel Pump 43gph @ 85psi from Trick Flow is engineered for builders seeking reliable, high-volume fuel delivery in modern EFI fuel injection systems. This pump addresses the critical need for consistent pressure and flow in carbureted-to-fuel-injection conversions, engine swaps, and custom fuel system builds where OEM pumps fall short. Whether you're upgrading a classic hot rod or building a high-performance street engine, this universal design eliminates fitment guesswork and delivers the flow rate required for responsive throttle control and stable idle characteristics.

Operating at 43 gallons per hour with regulated pressure of 85 psi, this pump supplies sufficient fuel for naturally aspirated and moderately boosted applications without excessive heat generation in the fuel system. The 85 psi pressure specification ensures stable fuel delivery across varying load conditions while remaining compatible with standard EFI fuel regulators and injector specifications. Trick Flow's engineering emphasizes durability and quiet operation, minimizing noise and vibration transmission to the vehicle frame—a key consideration in street-driven and show vehicles where fuel pump whine detracts from the driving experience. The compact 3.7 x 3 x 7.6-inch footprint and lightweight 1.73-pound design allow flexible mounting in fuel tanks, frame rails, or external fuel cell configurations without structural compromise.

Street rod builders, engine swap enthusiasts, and EFI conversion specialists benefit most from this pump's universal mounting compatibility and pressure-flow balance. Installation pairs seamlessly with aftermarket fuel rails, return-style fuel pressure regulators, and modern EFI controller systems. Verify your fuel system's total injector flow demand (typically 5–8 pounds per horsepower) and confirm that your regulator and fuel lines support 85 psi operation before final installation. This pump excels in applications ranging from 400 to 600 naturally aspirated horsepower and serves as an economical foundation for custom fuel systems where reliability and consistent performance are non-negotiable.
