I remove the fuel pump fuse or relay while the engine is running. The engine will run until the pressure has dropped. Leave the fuse or relay out until you have finished replacing the fuel filter.
fuel filter? fuel lines? what all have you checked.

Remove the gas cap. Look for a schrader valve on the fuel rail to release the pressure. If there is none then wrap the fuel filter connection and be prepared for a spray of fuel.

Relieve fuel system pressure. detatch filter bracket from the chasis. depress the plastic quick release tabs and detatch the lines from the filter. use one wrench to steady the filter and another to unscrew the fuel line fitting and remove filter.
