Automotive Tips: The Importance Of Fuel Filters

Most people don’t realize the importance of a fuel filter in the smooth operation of your car. It is often an overlooked but a critical component in good car performance, and if it becomes dirty and clogged, it can cause many unnecessary problems. Its purpose is to screen out debris, fuel tank rust caused by moisture, and dirt particles from the fuel.

Even miniscule paint chips from the car can get into the fuel when filling up at the gas station. Modern injection systems will then suffer, and an inefficient filter can negatively affect the fuel pump (which is very expensive to replace), and restrict the fuel to the engine. A clogged filter can also prevent valves from seating properly. Fuel will burn more efficiently the less debris it contains. A clean fuel supply to your car is vital.

There generally are two types of filters: inline filters which are underneath the car in the fuel line, and integral ones in older cars which are inside the carburetor where the fuel comes in. The best thing to do is consult your car owner’s manual for the exact location, or call the manufacturer of the car’s fuel pump for this information.

There are a number of opinions as when fuel filters should be replaced. Some say every 30,000 to 50,000 miles, and others say every two years. There are also some special filters which can be cleaned and used over and over. You can buy a fuel filter at an auto parts store, and you must tell the clerk your car’s make, model, and year. Sometimes information about the type of your car’s carburetor is also required. It is advisable to purchase a brand-name filter.

You may also want to get new clamps if they appear old or rusty. If you are mechanically inclined, you may want to replace the fuel filter yourself, but otherwise have a technician do it. Do not smoke and make sure there is no spark or flame close by. Also fuel injection fuel lines will spray gas all over the place if the pressure is not relieved first before disconnecting the line. The best way to do this is to let the car sit for many hours before disconnecting the line, although a little pressure may still exist, so be careful. Older cars have less pressure than fuel-injected ones but always be conscious of safety.

If a new fuel pump is installed, a new fuel filter should also be installed. After a fuel filter is replaced, be sure to start the car and check for leaks in both the hoses and the filter. Hoses when aging tend to get brittle and contain leaks and should be replaced immediately. A steel line can also leak. If you spot a leak, shut the car off immediately and under no circumstance start the car until the leak is repaired. As you know, gasoline is very flammable and dangerous.
