Specs At A Glance

Good To Know

Q: How do I know if this pump fits my vehicle? A: This is a universal external inline unit, so fitment depends on your fuel line routing and mounting provisions. Confirm inlet/outlet sizes and electrical connector style match your setup before ordering.

Q: Does a higher flow pump require other fuel system changes? A: A 255LPH pump often benefits from supporting upgrades such as a heavier-gauge power feed and an appropriately rated pressure regulator. Match the rest of the fuel system to the pump's output for best results.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
