Be very careful with the fuel filter, lives under the rear seat in the tank
From memory it has about 8 nuts holding it down
And from memory it's got a slight spring tension to it when being removed
So be wary of that
Keep the fuel level very low
When lifting up the fuel filter , take it very slowly
It will have fuel inside and will drain back into the tank
Don't forget
It also has an arm on it to show fuel level
This can be easily damage if your not careful
When lifting the filter up it may be easier to lean the filter over at a slight angle to get the arm out
Also
Before removing it in the first place
There is a power plug on top of the unit to power the pump
Remove that plug
Then start the car
It will run about 20 second or so
This will use up some of the fuel in the line and drop the line pressure
Then
Disconnect negative off battery
And very very careful remove the fuel line off the top of the fuel filter
Be a good idea to wear safety glasses to avoid getting fuel splashed in your eyes
You don't want that
Do it in a well ventilated area, away from sparks , and smokers
Grab a service manual and Read it also
Changing the filter won't upset anything to do with the ECU tune
However
If you change injector and put in bigger ones then yes , you will need to retune the ECU
Or
If you shove in a much bigger fuel pump then there is a good chance to retune as fuel pressure goes up.
