Show original supplier description
The Quantum Fuel System 340LPH Flextech series fuel pump is engineered for vehicles requiring over 600 horsepower. This intank pump provides a reliable fuel supply for demanding applications. It features a corrosion-resistant black plated steel construction with a serialized body for warranty tracking. Key specifications include an integrated check valve for efficient fuel delivery and E85 compatible corrugated flex hoses or submersible high-pressure rubber hoses, depending on the kit. Installation is aided by a thick 14-gauge universal pigtail and, where available, plug-and-play wiring harnesses. The pump is flow-tested by RC Engineering and includes a 40-micron strainer. This fuel pump can be utilized in both EFI and carbureted setups; however, carbureted applications will necessitate an aftermarket bypass-style regulator. Quantum backs every pump with a lifetime warranty, a commitment distinguishing it from many other 340LPH fuel pumps on the market.
