The Kemso 10910 is a 340 LPH high-performance electric fuel pump, engineered to support demanding applications of up to 700-800 bhp. This pump is suitable for naturally aspirated, turbocharged, and supercharged engines, and is compatible with both gasoline and E85 fuels. Designed as a direct OEM replacement for faulty stock pumps, the Kemso 10910 offers enhanced flow capabilities compared to popular alternatives like the Walbro 255 GSS342, while maintaining similar physical dimensions. Its bypass valve is set higher than many comparable pumps, operating at 125.8 psi. The kit includes the genuine Kemso 340 fuel pump, two gradient density fuel strainers with a lock ring, a flex hose, a rubber hose, a wiring connector, crimp connectors, hose clamps, a rubber base, and zip-ties. The fuel pump body is serialized, guaranteeing a lifetime warranty.
