Fuel filter

So my inline fuel filter is leaking and its gotta go. 4 banger turbo 87 T5. This will be my first time replacing the filter so I'm clueless on how to do it. I just know depressurize the fuel system, take off the duck bill clamps and I think there is one of those clamps that you rachet off too. My questions are:

1. How do you depressurize the system?
2. Along with the filter, are there any other parts I should get for this job?
3. I'm pretty sure if I'm depressurizing I have to repressurize..is there a method to that?

If there is anything else that I'm missing let me know please!!!

1. To get rid of the pressure in the lines, cover the schrader valve on the fuel rail with a rag and press in on the center with a small screwdriver or something. Fuel may spray out when you do this depending on how well you cover the valve. Wear eye protection. Also, there will still be fuel in the filter and lines so be prepared for it to pour out when you remove the lines from the filter.

2. You shouldn't need anything else. The new filter will probably have the new plastic clips for the fuel lines in because the old ones might be brittle and break when you try to take them off.

3. The system will pressurize when the fuel pump primes before starting the car the next time. I usually cycle the key a couple of times just to be sure.

I just depressurize it by running it out of fuel by unplugging the fuel pump relay or tripping the inertia switch lol

I think thats the proper way.. good to test the inertia switch too, I just tap it with a screw driver handle a couple of times and it trips
