Emglo / Jenny GU, GCU, LU, LCU, MGU Air Compressor Pump Rebuild Kit #057681

Complete rebuild kit for entire air compressor pump. Includes the piston rings, gaskets, intake and exhaust valves, unloader valves, and canister-style air filter elements (L54E hollow-style) for the GU, GCU, LU, LCU, and MGU Pumps.

If you have a sudden loss of performance, if air leaks out of the intake filter, or if the compressor just isn't performing like it should, order this kit. A loss of pressure or slow pressurization is usually caused by either damaged compression rings, gaskets, and/or damaged or sticking valves.

Remember to tighten the bolts down to the proper torque specs as noted by the manufacturer.
