Chevrolet Truck Fuel System Problems

Clogged filters can advance to Chevrolet Motor lorry fuel system problems.

Chevrolet trucks can develop common fuel system problems, which can often be resolved via basic troubleshooting techniques.

Fuel Pump Failure

Chevrolet truck fuel pumps transfer fuel from the tank to the carburetor and engine. Inspect the air filter for sediment buildup and replace it as needed.

Clogged Fuel Filter

A dirty or clogged fuel filter, often the result of age, can result in rough idle, engine hesitation or failure to start the engine. Change the fuel filter and replace it every five years, or 50,000 miles, as part of the routine maintenance schedule.

Clogged Air Filter

A dirty air filter, especially susceptible to clogging during muddy or dusty driving conditions, can result in reduced or no air reaching the engine. This can cause a high fuel ratio in the combustion mixture, resulting in higher emissions and poor engine performance. The pumps can fail due to age, wear or leaks, resulting in engine stalling or failure. Check the fuel lines for leaks and replace any worn or torn lines. Then, check the fuel pump with a fuel pressure gauge, which attaches to the Schrader valve. If the fuel pressure fails to reach acceptable limits, per your owner's manual, replace the fuel pump.
