Diesel Fuel Storage and Testing
Along with starting batteries, fuel is the most common reason an emergency power supply (EPS or “generator”) fails to start. Problems with the fuel system stem mainly from foreign matter such as fine abrasives, water, and “coagulated” aging fuel. These contaminants cause reduced performance and expensive repairs, not to mention preventing the generator from starting in […]
