ISR Performance High-Pressure 255 ltr/hr Fuel Pump Nissan 240sx 89-98

The ISR Performance High-Pressure 255 lph Fuel Pump is the proven baseline fuel system upgrade for the Nissan 240SX, especially for SR20DET swaps and high-horsepower builds. Based on the GSS341 platform, it ships with a Nissan-specific install kit for direct in-tank fitment.

What It Does

The factory fuel pump on the Nissan 240SX is rated for stock power levels. As soon as you add boost, larger injectors, or build the motor, the stock pump becomes a bottleneck and can't keep up with fuel demand. The ISR 255 lph pump increases fuel flow capacity to support significantly more power and maintains consistent fuel pressure under load, keeping air-fuel ratios stable when you're on boost.
