in the gas tank
drop the tank.......
I have a 1985 celica GT and the fuel filter is located above the oil filter on the engine block. If the ST model has a 22re engine it should be the same.
The fuel filter location is inside the fuel tank along with the fuel pump in order to get to it you have to remove the back seats there's a video on youtube on how to do it just type in "Replacing fuel pump / filter on toyota celica Gt'' but the fuel filter can only be bought via internet because no auto part store carries it.
The fuel filter is located on the drivers side under but close to the air filter and the brake master cylinder.
The fuel is going to be connected to the fuel line, first find the fuel line and follow it, and you should find be able to find the fuel filter.
The fuel filter for 2002 and all 7th Generation Celicas(2000 thru 2005) is located inside the fuel tank
If it is an 89 st model with the 3sfe or 2.0l the fuel filter is located on the driver side just below the master cylinder.
It's down on the side of the driver's side engine compartment.
The fuel filter is located under the vehicle near the fuel tank and is connected to the fuel line. The oil filter is located behind the wheel well on the passenger side of the vehicle.
THERE IS NO FUEL CUT OFF SWITCH ON YOUR CELICA
Right under the intake on the passenger side of the engine, near the firewall but still on the motor.
