Show original supplier description
The Quantum Fuel System Hanger is an in-tank fuel pump hanger with a sending unit, specifically designed as a clean-sheet solution for 1973-1991 LS or LT swapped Square Body pickups. This hanger facilitates the installation of popular fuel pumps such as the EP381, 255LPH, or 340LPH without the need for splicing connectors within the fuel tank, enhancing reliability and simplifying the swap process. Constructed with a corrosion-resistant coating, this hanger features 6AN fittings for secure connections and includes a submersible high-pressure hose compatible with both gasoline and ethanol-based fuels like E85. It comes with wiring pigtails designed to fit the AC Delco EP381 and a 14-gauge "Walbro style" pigtail for 255LPH/340LPH pumps, along with a plug-and-play adapter harness for the EP381. An integrated check valve is built into the fuel pump outlet for optimal performance. Benefits of this hanger include the elimination of failure-prone splices and solder joints inside the fuel tank, offering a safer LS/LT swap for your Square Body pickup. It is compatible with any LS, LT, or EFI motor, with an optional filter add-on providing standard Corvette pressure of 58psi. Quantum backs this product with a lifetime warranty on both the fuel pump and the sending unit.
