Where is the fuel filter located on a 2001 Mazda Protege?
From the look of things theis car does not have a fuel filter. The only filter that has to do with the fuel seems to be in the fuel tank. A 2001 Mazda Protege (actually, all models from 1999-2003 including the DX, LX, ES, Mazdaspeed, and Protege 5) does not have an inline fuel filter. The only fuel filter it has is a "strainer" or a "screen", which looks like a nylon mesh "sock". This strainer is connected to the fuel pump, located in the gas tank. Although this fuel strainer does not require periodic replacement, it is recommended that it be changed if you are replacing the fuel pump.
A 2001 Mazda Protege has a seal system, meaning the car does not have a dipstick to check the transmission fluid. It is best to take it to a dealership to have the fluid tested, but a person can check it by slightly pulling out the plug under the car, and see the condition of the fluid coming out of the plug.
