Detroit Diesel Corporation has collaborated with ESOC (Environmentally Safe Oil Change) Commercial Truck Inc. to develop an environmentally safe fuel filter change system for its DD15 and DD13 engines. ESOC is a Michigan corporation that has been serving Detroit Diesel since 1994 with environmentally safe engine maintenance systems.
The ESOC 350 was developed to prime the fuel system after the high-pressure fuel pump replacement occurs. This device was designed to prime the fuel system with the fuel pressure being at least 70 psi for a minimum of two minutes to meet OEM specs. The ESOC 350 can also be used to prime the fuel system after a fuel filter change. One of the attributes of this device is to use the fuel from the engine, eliminating an outside source to fill the device with diesel fuel.
Another key benefit of the ESOC system is that it is safer for both technicians and the environment. The spill-free machine removes hazardous waste cleanup and eliminates the need for technicians to handle the fuel.
