70750 06AN High Flow Fuel Return Kit

This 06AN High Flow Fuel Return Kit is required for use with 255lph fuel pumps. The 1/4" return port in the 5.0 Mustang factory style EFI fuel pump bracket does not properly handle the return flow of 255lph fuel pumps. The small diameter causes two problems. First being the high flow velocity which aerates the fuel in the tank baffle causing vapor bubbles to be ingested by the pump. Second is the excessive back-pressure created by the flow restriction which can cause excessive and varying fuel pressure. Both wreak havoc on engine tuning and driveability.
