Auto Select's Guide to Fuel Filters - Save Money by Changing Your Filter

Auto Select's Guide to Fuel Filters - Save Money by Changing Your Filter

The function of a fuel filter is pretty self-explanatory.  It filters your fuel.  The fuel filter is in the fuel line somewhere in between the fuel tank and the engine.  Both gas and diesel vehicles use fuel filters.

There’s not a lot of dirt in the fuel supply, but there is enough that you want to screen it out.  The problem gets worse the older your vehicle becomes.  That’s because dirt, rust and contaminates will settle out of the fuel and onto the bottom of the fuel tank.  After a car is five years or older, it can have a fair amount of sediment built up. 

That just means that the fuel filter must work harder as your car ages.  It’ll get clogged sooner and need to be replaced more often.

A symptom of a clogged fuel filter is that the engine sputters at highway speeds or under hard acceleration.  That’s because enough fuel is getting through around town, but when you need more fuel for speed, enough can’t get through the filter.  Obviously, that could be dangerous if your car or truck can’t get enough power to get you out of harm’s way.

For just that reason, fuel filters have a bypass valve.  When the filter is severely clogged, some fuel can bypass the filter all together.  Of course, that means that dirty, unfiltered fuel is getting through to be burned in the engine.

This dirt can then clog and damage your fuel injectors.  Now injectors are not cheap to replace, so you don’t want to cause them damage just because you didn’t spend a few bucks to replace a fuel filter.

You know, in a way, the fuel filter can be the poster child for preventive maintenance.  It’s a little part, it’s simple and it’s cheap to take care of.  But if it’s neglected, it could lead to thousands of dollars of repair bills.

During your next service at Auto Select, make sure to ask about your fuel filter.
