Fuel Pump - 255lph - Gas Inline - Universal

The Walbro GSL392 255 LPH gas inline fuel pump (SKU: WFPGSL392) is a high-flow electric fuel pump engineered for gasoline-powered vehicles requiring robust fuel delivery at elevated pressures. Manufactured by Walbro/TI Automotive—an OEM supplier trusted by factory vehicle programs—this pump delivers 255 liters per hour, making it a common choice for naturally aspirated and forced-induction engine modifications where factory fuel supply proves insufficient. The inline design allows flexible installation in fuel tanks or external mounting configurations depending on your fuel system architecture.

Rated at 255 lph, this electric fuel pump supplies the volume necessary to support higher fuel injector flow rates and engine power levels beyond stock specification. The 10 mm x 1.00 female inlet and outlet ports accept standard automotive fuel line fittings, simplifying integration into existing or custom fuel rail systems. At 1.13 lbs and compact dimensions (2.35 x 2.3 x 7.35 inches), the pump fits tight packaging constraints common in engine bay modifications. This GSL-series pump is designed for use with unleaded gasoline and operates at the electrical specifications required by 12-volt vehicle systems.

Buyers pursuing fuel system upgrades—whether for turbocharged applications, carbureted conversions, or fuel-injected engine swaps—rely on Walbro pumps for consistent pressure regulation and long-service life. The 255 lph output bridges the gap between stock fuel delivery and serious performance builds without requiring massive displacement engines. Installation requires attention to electrical grounding, fuel line routing, and pressure regulation to prevent over-fueling or component damage. Verify pump compatibility with your specific fuel injector size, rail pressure requirements, and vehicle electrical architecture before ordering.
