This Electric Pressure Control Valve Kit is for a discharge/refill of 35-40 PSI. These valves have the convenience of an electric valve for remote mounted units and the rapid refill rate of a manual valve as required in racing. The E.P.C. valving will only allow the Accusump to discharge oil when the engine's oil pressure drops below a predetermined level and only refill when the pressure rises above that level. Comes with the regulator, electric valve, a pipe nipple, a toggle switch, wire, terminals and instructions.
