J-47912 Fuel System Priming Pump for Detroit Diesel, 3 Gallon

Air trapped in a diesel fuel system after maintenance can lead to extended cranking, difficult starting and unstable engine operation. The FISHFRUIT J-47912 Fuel System Priming Pump provides an external source of pressurized diesel fuel to help fill the system and remove trapped air before the engine is restarted. It is designed for common Detroit Diesel service applications, including DD13, DD15, Series 60, MBE900 and MBE4000 engines. It also supports listed MaxxForce 11 and 13 applications from 2010 and N13 engines equipped with SCR from 2013. The tool serves as an aftermarket alternative to J-47912, OTC 5869, 12-922-01 and 15-922-01 service tools. The complete kit includes a 3-gallon stainless steel tank, manual pump, pressure gauge, 6 ft fuel hose, Compu-Check quick connector and carrying strap. The large reservoir is suitable for professional maintenance procedures, while the gauge allows the operator to monitor pressure during priming. Recommended applications include fuel filter replacement, drained fuel systems, fuel-line or injector work, air-in-fuel diagnosis and returning stored equipment to service. It is intended for diesel repair shops, dealership service departments, fleet maintenance facilities and mobile heavy-duty technicians. Compatibility can vary by engine year and fuel-filter module. Confirm the engine model, year and priming-port configuration before purchasing. Use only with diesel fuel and follow the engine manufacturer’s procedure and the included filling, pressure and depressurization instructions. Never use with gasoline.
