Fuel Pumps

The regulated modules are complete assemblies with a built-in fuel pressure regulator, fittings, and a returnless single fuel line design. Replacement in-tank pumps are just the pump itself, designed to swap into an existing Go Fuel module when the original pump wears out.

An in-tank pump sits inside the fuel tank where it runs cooler, quieter, and with less risk of vapor lock. An external inline pump mounts on the frame outside the tank and feeds through a supply line and return line. In-tank is the cleaner install. External is simpler if you don't want to modify your fuel tank.

Match the pump to your power level. 255 LPH covers lower HP applications, 340 LPH handles most street and performance builds, and 440 LPH supports higher HP setups. Check the product listing for specific HP ratings.

The regulated in-tank modules include a built-in 58 PSI fuel pressure regulator and will work with most EFI systems that run at that pressure. The inline external pump and replacement in-tank pumps deliver high-pressure fuel but may require an external fuel pressure regulator when used with non-FiTech systems.

Common signs include hard starting, loss of power under load, inconsistent fuel pressure, or the engine stumbling at higher RPM. If your fuel pressure drops below what your EFI system requires, the pump is the first thing to check. Contact tech support if you need help diagnosing a fuel pump problem.
