ProStar SQ 750 Electric Fuel Pump

The ProStar SQ 750 Electric Fuel Pump is a high-capacity in-line fuel delivery system designed for modern EFI applications requiring consistent, adjustable pressure across a wide operating range. Operating between 20–120 PSI, this electric fuel pump delivers the flow and regulation needed for naturally aspirated and forced-induction fuel-injected engines, making it suitable for street vehicles, off-road platforms, and performance builds running E85 or conventional gasoline.

This pump features 10 AN female o-ring inlet and outlet ports, allowing direct integration into custom fuel systems with minimal adapter requirements. The adjustable pressure range accommodates engine tuning flexibility—whether maintaining idle stability at lower pressure or supplying fuel demand under full load or turbo boost. The 750 designation refers to the pump's flow capacity, enabling adequate fuel supply to mid-sized naturally aspirated engines or smaller forced-induction platforms. E85 compatibility expands fuel choice for builders pursuing ethanol blends, which require higher flow rates than gasoline due to lower energy density per gallon.

Builders integrating the ProStar SQ 750 into custom fuel systems—whether street rods, LS swaps, water-cooled performance vehicles, or off-road recovery platforms—benefit from the pressure adjustment range and fuel-type flexibility. The in-line configuration suits applications where tank-mounted space is limited or where centralized fuel regulation upstream of the injectors simplifies diagnostics and tuning. Proper fuel line sizing, regulator setup, and electrical grounding are essential for reliable operation and longevity in any build.
