CRD Universal Auxiliary Fuel Pump Harness

This harness is engineered to supply power to an external fuel pump in supercharged or turbocharged systems, or to replace a defective auxiliary pump harness. It also supports building a custom auxiliary fuel pump setup. Pre-wired for seamless plug-and-play operation with a Hobbs Switch (pressure switch). A boost reference line connects from the intake manifold or supercharger pressure side to the Hobbs Switch. The harness features 12-gauge wiring capable of handling any external pump load, is prewired for Walboro pumps, and includes a 20-amp fuse. Sealed weather pack connectors protect against dirt and moisture, while a serviceable 40-amp relay ensures durability and serviceability.

Included are a 7 PSI Hobbs Switch (4 PSI option available), plus a 3/16 reference hose and fittings.
