Fuel Pump Kit - 190lph Gas - Inline - Universal

The Fuel Pump Kit - 190lph Gas - Inline - Universal from WALBRO / TI Automotive is engineered for builders and enthusiasts upgrading to forced induction or higher fuel demand applications. This kit delivers 190 liters per hour at 43.5 PSI—sufficient for naturally aspirated performance builds and entry-level boost scenarios up to approximately 300 whp. Whether you're installing a turbocharger, supercharger, or maximizing fuel delivery in a carbureted conversion, this universal inline pump eliminates the guesswork of fuel starvation under acceleration, ensuring consistent atomization and combustion across the RPM band.

WALBRO's GCL620-4 pump uses proven brushless motor technology and internal check valves to prevent fuel backflow and vapor lock during hot-soak conditions. The inline configuration mounts directly in-tank or in-line within your fuel system, offering flexibility for custom fuel cell or OEM tank applications. At 190 lph output, the pump provides ample margin over stock fuel system capacity without oversizing—excessive flow can compromise fuel pressure regulation and cause carburetor flooding or injector issues. The compact form factor (4.15 x 4.15 x 4.45 inches, 1.48 lbs) fits tight engine bays and allows integration into existing fuel lines with standard push-to-connect or barbed fittings.

This pump excels in street rods, LS swaps, vintage truck restorations, and turbo four-cylinder platforms where OEM fuel delivery falls short of modified engine demands. Universal fitment allows installation in most gasoline-powered vehicles; however, verify your fuel line diameter (typically 5/16-inch or 3/8-inch) and tank configuration before purchase. Pair this kit with an appropriately sized fuel pressure regulator (typically 45–50 PSI for carburetors, 40–43 PSI for port fuel injection) to optimize performance and protect downstream components. Proper grounding and a quality in-line fuel filter are essential to maximize pump longevity and system reliability.
