A 340 lph fuel pump kit for the 1989-1993 NA Miata, built to run E85. If you're boosting a 1.6 car or switching it to ethanol, fuel delivery is the first ceiling you hit — this pump is application-specific for the early NA and comes with its installation kit and filter, so it's a drop-in job rather than a universal-pump fabrication project.

ISR builds these pumps with composite impellers for corrosion protection on E85, which is what kills ordinary pumps on ethanol over time. Verify the rest of your fuel system is E85-ready before you switch fuels — the pump is only one part of that equation.

• 340 lph flow rate
