ISR Performance 415 lph E85 Compatible Fuel Pump Kit Universal

The ISR Performance 415 LPH E85-Compatible Fuel Pump is the higher-flow option in our universal fuel pump line. Built for high-horsepower forced induction builds running E85 or gasoline, with composite impellers that resist the corrosion issues that kill standard fuel pumps on ethanol fuel.

What It Does

Fuel pumps move fuel from the tank to the engine. As power demand goes up, fuel flow demand goes up. and the factory pump runs out of capacity well before high-hp builds run out of engine. The 415 LPH flow rate covers most high-hp builds on either gasoline or E85. The composite impeller construction is the meaningful spec for E85 use: ethanol is mildly corrosive to metals over time, and composite impellers eliminate that wear mode entirely.

Fitment

Universal. The pump itself is universal-fit; you'll need to verify the included installation kit matches your specific in-tank pump housing. For application-specific kits, see our chassis-specific variants (e.g., IS-FP415-NA for 1989-1993 NA Miata).
