2003 Toyota Camry Change the Fuel Filter
The fuel system on the 2003 Toyota Camry comes equipped with a canister-type fuel filter. This fuel filter is made to keep small particles and debris out of the engine. The canister fuel filter has a inner filter through which the gas travels. Once the gas travels through the inner filter, the filter will trap and hold the small particles and debris inside. Then, the clean gas will flow through the fuel lines to the fuel injectors and into the engine. Replace the fuel filter between 40,000 and 75,000 miles.
