Buick Rainier Fuel System Parts

If you discover that your Buick Rainier starts consuming more gas than usual, there may be a number of reasons for such behavior. If you did a thorough check-up and made sure that your spark plugs were in great working order, tires were inflated correctly, and air filter was in good shape, then you have grounds to blame the fuel delivery system. The fuel injectors that perform the function of delivering pressurized gas into the engine may leak and waste fuel. A faulty fuel pump can cause excessive pressure and move more gas than required.

Doubtlessly, poor gas mileage is not the only symptom of the malfunctioning fuel delivery system. Whether the fuel is improperly filtered or transferred at incorrect pressure, it causes poor engine operation and can lead to a stressful situation when the vehicle won't start.
