There are several parts to the fuel system, including the fuel pump, fuel filters, injection lines, and, on older vehicles, the carburetor. Today, our ASE-certified technicians in Omaha are answering common questions about the fuel system.

How can I tell my fuel pump isn’t working?

Our experts generally only see this problem in vehicles with 60,000 miles or more. There’s always a chance that there’s a different problem with another engine component.

Signs the fuel pump isn’t working include:

• Sputtering sounds
• Loss of power when accelerating
• Stalling
• Failure to start

To verify the fuel pump is working, have someone turn the key of your car just so that they battery comes on. While your friend does that, take your gas cap off and listening to the opening. You should be able to hear the fuel pump hum for two or three seconds after the key is turned, if it’s still working.

If you turn the key and don’t hear the hum of the fuel pump, call our fuel system experts in Omaha for a diagnosis.

What can I do to prevent fuel system damage?

The best way to make sure fuel is properly pumped to the engine is to keep the system clean. Fuel filters are in place to make sure debris doesn’t enter into the fuel system. However, if these become clogged or worn, debris will contaminate the system and put stress on it.

Another tip: never fill up on gas when a tanker-truck is filling the station tanks. This will stir debris-particles that have settled and they will find their way to your own gas tank.

When should I service my system? 

Our automotive specialists recommend a complete fuel system cleaning every 15,000 miles, or once a year, to keep everything running smoothly. If you start to notice your car using more gas than usual, or your car doesn’t accelerate fast enough on the highway, call Christian Brothers Automotive in Omaha, Nebraska.
