Show original supplier description
The Quantum Fuel Systems QFS-340FT is a 340LPH Flextech series in-tank fuel pump engineered for vehicles exceeding 600 horsepower. It is built to the same proven standards as other leading 340LPH pumps and offers enhanced durability with a corrosion-resistant black plated steel coating and a laser-etched serial number. Key specifications include a flow rate of 324 LPH at 45 psi and 298 LPH at 60 psi, with an amperage draw of 11.8 amps at 45 psi and 12.9 amps at 60 psi. The pump features an integrated check valve at the outlet for optimal performance and reliability. It is compatible with both EFI and carbureted systems, with the understanding that carbureted applications will necessitate an aftermarket bypass-style regulator. Installation is facilitated by a thick 14-gauge universal pigtail and included plug-and-play wiring harnesses where available. The pump comes with either corrugated E85-compatible flex hoses for GM and BMW kits or submersible high-pressure rubber hoses for other applications. Each pump is independently flow-tested by RC Engineering and comes with a serialized body to guarantee a lifetime warranty, a commitment Quantum Fuel Systems makes across its entire line of OEM and performance fuel pumps.
