you can depresure the system by pushing in the schrader valve on the fuel rail. or you can wait awile after you shut the car off then do it without depresurizing
you guys can do that.. but i have never released the fuel presure on any fuel filter i have done.. and as long as it was shut off for 15 minutes or so it was fine.
if you pull the line right after you shut it off you will get sprayed. no matter what you do some fuel will come out
I just installed a Purolator filter on my GT that I picked up at AutoZone (Motorcraft was out of stock). I also picked up the spring release tool while I was there which made the install a breeze. I pulled the fuel pump fuse and ran the car for a few minutes, not till it stalled but just to relieve the pressure. Only had a few ounces of fuel spill out.
what i do is open the trunk with the car running and give the kill switch sensor a good whack with a ratchet. after about 10 seconds the car dies on its own. that generally releives all the pressure becasue the kill switch turns off the fuel pump in case of an accident. once i change the filter, i push the button back in and the car starts fine.
