How can one prolong the life of a fuel pump in an automobile? Are there certain things that can be done with out removing the tank to keep the pump clean?
Fuel pumps can go out gradually or all at once like any pump they are not invincible. This can leave one stranded and probably at a most inopportune time.
Here is a list of certain things one can do to prolong the life of the pump and keep the vehicle owner in a better mood:
Thing 1: Do not consistently run the fuel tank on empty even if in a vehicle that is rarely used. This will cause the fuel pump to pull up sediment from the bottom of the tank and this could clog the screen that is on the rod that goes to the pump.
Sediment can be caused by metal flakes from inside the tank or deposits that come from gas station tanks. Either way there are deposits in the tank and they are usually vacuumed in when the tank is at its lowest point.
Thing 2: Engine additives can cause the same thing to happen which are sediment deposits in the gas tank. Some additives can cause deposits inside the tank to become solvent and settle to the bottom of the tank and eventually onto the strainer causing the pump to shut down.
There are enough deposits that occur from just fueling the engine and water in the gas which is corrosive. We should not try to speed the process along by adding things that should not be there. Watch what goes into the tank and make sure it is recommended for the vehicle that you drive.
Thing 3: This one involves taking the tank off bi-annually and cleaning it out manually. This way all of the deposits can be removed and the tank will be just like new. This method takes the worries of running the tank on empty and putting additives in the vehicle are reduced substantially.
Taking the tank off and cleaning it out in this style works but taking precautions 1 and 2 will work too.
Taking care of the gas tank will not only keep the fuel pump from failing but everything else that is in line with it. A clean fuel pump is good for the filters which in turn is good for the carburetor or fuel injectors.
