Diesel Fuel System Stress Makes Maintenance Essential
Unlike gas-powered vehicles, where an electrical spark causes fuel combustion, diesel engines use high compression to squeeze air down to 1/15 to 1/20th of its usual volume and ignite fuel. Your fuel (transfer) pump serves as the system’s heart, pulling diesel from the fuel tank and circulating it through a fuel filter to remove water and contaminants that could impact combustion. Fuel lines then transport diesel fuel to the injection pump, where it’s compressed and injected via nozzles into your engine cylinders. Once hot enough to burn, combustion propels the piston, turning the tiny explosions into mechanical energy that powers your vehicle. Optimum operation of all components ensures peak performance.
Watch Out for these Signs of Diesel Fuel Pump Issues
Your diesel truck engine relies on a steady fuel supply to maintain smooth operation. When your diesel fuel pump can’t deliver, it may show these common signs and symptoms indicating the need for repair or replacement:
- Squeaks and squeals
