Fuel Pump - 190lph - Gas Inline - Universal

The Walbro GSL394-3 Fuel Pump – 190 lph Gas Inline is a high-performance electric fuel pump designed for gasoline-powered vehicles requiring serious flow capacity for naturally aspirated or moderately modified engines. This universal inline pump delivers 190 liters per hour at 43.5 psi, making it a reliable choice for street performance builds, fuel system upgrades, and custom fuel system applications where OEM pumps fall short of flow demands.

The GSL394-3 features 10mm x 1.0 female inlet and outlet connections, accommodating standard fuel line sizes used across domestic and import platforms. At 190 lph output, this pump supports engines in the 300–350 naturally aspirated horsepower range without restriction, ensuring consistent fuel delivery under load and acceleration. The compact inline design (measuring 2.3 x 2.2 x 7.45 inches and weighing just 1.12 lbs) allows flexible mounting in engine bays, fuel tanks, or fuel lines where space is limited. Walbro's proven engineering and TI Automotive's quality standards make this pump suitable for long-term reliability in custom fuel systems.

This pump is ideal for builders upgrading fuel delivery on carbureted or fuel-injected engines, street rods, restorations, and performance vehicles where factory fuel supply is inadequate. It's a bolt-in replacement for custom fuel system installations and works well paired with aftermarket fuel rails, regulators, and filtration. The universal configuration means buyers must verify inlet/outlet port compatibility with their specific fuel system plumbing before installation.

For high-flow fuel delivery on gasoline engines, the 190 lph Walbro GSL394-3 strikes a balance between performance and cost-effectiveness, offering a proven platform trusted across the motorsports and custom car building community.
