When do you change fuel filter

Ultimately, a faulty filter could see you stranded by the roadside with a broken-down car so it's important to get a fuel filter replacement when required. This equates to around two years of use. If you have a very new car, you may find you can drive further than this without needing to replace the filter.

The only sure way of telling if your fuel filter needs replacing, however, is to have it checked over by a mechanic, who will conduct a fuel-pressure test. This test will reveal how much PSI the fuel pump is creating at the fuel rail.

An expected amount of pressure in a regular fuel-injected vehicle is between 30 to 60 PSI. Anything lower than this suggests your require a fuel filter change. In some instances it may not be obvious where the filter is located. However, by following the fuel supply line it should be pinpointed fairly quickly.

The location of your fuel filter depends on the layout of your car. Some are mounted in the fuel line, while others are positioned in the tank. On an older car, the fuel filter is usually connected to the firewall, or underneath the rear, next to the fuel tank. It may be trickier to locate - and replace - the fuel filter on a newer car, since they are normally inside the fuel tank itself. Search Our Stock. Featured News. Winter Car Care Tips.

Throttle Body Service — The throttle body is a butterfly valve located between the air intake filter and the intake manifold and opens or closes, allowing air into the engine, based on the speed determined by the vehicle driver by pressing the accelerator. Fuel varnish builds up in the throttle body allowing the butterfly valve to remain slightly open, affecting the idle and decreasing overall fuel economy.
