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. If the fuel system of your car shows signs of wear and tear or has leaking, clogged, or brittle components, it's time to glance at our extensive collection of premium quality Buick Rainier fuel delivery parts. A remarkably wide range of top-of-the-line products, from high-class replacement fuel pumps to fuel injectors, is at your disposal to achieve maximum performance for minimum cost.
