Mazda 323 fuel filter?
The Mazda 323 fuel filter is located in the fuel tank. The fuel tank will need to be drained in order to change the fuel filter.
This should be the same as the 1989 323; the curved connection is the outlet end to the carb or fuel injector pressure regulator. The straight end connects to the fuel line from the fuel tank. The filter should also have an arrow marked on it for fuel direction flow. Cheers Malcolm He means the curved part goes to the top.
