QFS-340FT 340LPH Racing Performance Intank Fuel Pump with Installation Kit Supports over 600 BHP in N/A, Turbocharged, and Supercharged applications Designed and constructed to balance volume, pressure, and turbine impeller angle to prevent overheating of fuel--and problem free operation in excess of 100,000 miles HFP Support for QFS pumps is USA based and provided by USA technicians. Ships from the USA. HFP pumps exceed OEM specifications in fit, form and function Unless you want exceptional racing performance, you should consider the OEM replacement kit HFP-361 Correct strainer shape and orientation ensures the pump does not suck air, fuel tank or cell can be run to empty just like an OEM pump. Wiring pigtail designed to handle increased amperage draw of the 340LPH fuel pump, unlike competitors&#039; wiring which includes thin/ unsafe 20 gauge pigtail. GM/ Subaru/ Honda plug and play wiring harnesses available and included with pumps.More being developed continuously. Corrugated E85 compatible flex hoses included for BMW, custom, and GM kits. Flowtested by RC Engineering, the nationwide experts in fuel pump and injector flowtesting. Four different inlet configurations depending on application; 22mm (3/4&#034;) center inlet (QFS-340FT) 11mm (0.433&#034;) offset inlet (QFS-341FT), 11mm (0.433&#034;) parallel inlet (QFS-342FT), 19mm (0.748&#034;) offset GM inlet (QFS-343FT) 8mm (0.315&#034;) outlet w/ barb, 38mm (1.540&#034;) pump body diameter Coating: corrosion resistant black plated steel w/ laser etched serial number. Bypass valve (PRV valve) set at 125.8psi, significantly higher than both Walbro GSS series 255LPH pumps, and Walbro 400/ 450LPH pumps, a distinct advantage for turbocharged and supercharged applications Intank/ submersible design, cannot be used outside of tank May be used with return or returnless fuel systems, including PWM (pulse modulated systems) Designed for gasoline or E85, although E85 may shorten lifespan. Integrated check valve built into fuel pump outlet. 11.8 amps @ 43.5PSI (13.5VDC) 12.8 amps @ 58.0PSI (13.5VDC) 14.4 amps @ 80.0PSI (13.5VDC)
