Fuel PumpFeb 22nd, 2018
Your fuel pump sends fuel from the fuel tank to the engine. Fuel pumps just wear out over time; it might be the electric motor, a sensor, a valve, a relay or some other electrical component. Whatever the exact cause for the fuel pump failure may be, the solution to getting you back on the Santa Rosa road is to replace the pump assembly. When one component has failed, another one is probably just around the corner, so it makes sense to replace everything at once and save the future labor costs.
The fuel pump is inside the fuel tank on most vehicles, and for many cars, trucks and SUVs, the fuel tank must be removed to replace the fuel pump. As you can imagine, that is pretty labor intensive: removing heat shields, retaining straps, all of the EVAP lines, fuel lines and electrical connections. And, of course, there is properly and safely handling the fuel that must be drained from the tank.
Some vehicles have an external fuel filter that should be replaced at the same time. The fuel tank may need to be replaced on some vehicles because of design specifications or if the fuel tank is corroded or otherwise damaged.
Now there are a couple of things you can do to help your fuel pump last longer. One pump killer is contamination in the fuel tank. Sometimes this comes from the fuel itself. Buying fuel at a reputable station will help make sure you are putting clean fuel into the tank. Older vehicles tend to have more sediment in the tank from years of rust or corrosion from the tank itself. The tank may need a thorough cleaning or replacement.
Another thing you can do is refill your tank when it gets down to about a quarter full. The fuel pump is submerged in the fuel which cools and lubricates it. When the tank runs low, the pump has to work harder to suck up the fuel from the bottom and there is no fuel to cool it. This can lead to premature wear.
When the day comes that your fuel pump needs to be replaced, Greentech Automotive in Santa Rosa will use a quality replacement pump that meets or exceeds your vehicle manufacturer’s specifications. The entire assembly should be replaced. We'll be sure to install a replacement pump that is compatible with your fuel type. For example, if you have a FlexFuel vehicle that can run on gasoline with up to 85% ethanol content, your fuel system components – including the fuel pump – must be able to withstand the corrosive effects of high alcohol content fuel.
