Check Valve ensures all the oil being discharged out of an Accusump goes to lubricate the engine bearings and is not fed back toward the pump. For use in systems where a remote oil filter or a cooler is used. Uses 1/2" N.P.T. female threads.
This liquid filled Accusump gauge is an upgrade to the standard gauge. This gauge features a larger dia. stainless steel case and is less effected by vibration. Recommended for severe duty and marine use.
