Frequently Asked Questions
What flow rate do I need for my racing fuel pump?
The required flow rate depends on your engine’s horsepower and fuel type. A general rule is 0.5 LPH per horsepower for gasoline, and 0.7 LPH for E85. For a 600 HP engine on gasoline, you would need at least 300 LPH. Always leave a safety margin of 20-30% to account for pressure drops and future upgrades.
Can I use a racing fuel pump with E85?
Not all racing fuel pumps are compatible with E85 due to its corrosive nature and higher flow requirements. Look for pumps specifically rated for E85, such as the Aeromotive A1000 or Walbro 525LPH. Pumps with stainless steel internals and ethanol-resistant seals are recommended.
Should I choose an in-tank or external fuel pump?
In-tank pumps are quieter, cooler, and easier to install in many vehicles, but they may be limited by space. External pumps offer higher flow and easier servicing but can be noisy and require proper mounting and filtration. For street-driven race cars, in-tank is often preferred; for dedicated race cars, external pumps are common.
Do I need a fuel pressure regulator with a racing pump?
Yes, most racing fuel pumps are designed to run at a constant pressure only with a regulator. A bypass or dead-head regulator ensures the correct pressure for your fuel system (e.g., 43 PSI for carbureted, 58 PSI for EFI). Without a regulator, pressure can spike and damage components.
How do I wire a racing fuel pump safely?
Racing fuel pumps draw high current, so use a relay triggered by the ignition or an oil pressure switch. Use appropriately sized wire (10-12 AWG) and a fuse rated for the pump’s maximum draw. Ensure the pump is wired to shut off if the engine stalls to prevent fuel leaks in an accident.
