I think You are supposed to relieve the pressure I have never done this all I do is wait awhile after I have last run the car,It really I isn't a big deal.Don't worry about the fuel that comes out but do try to catch it. you don't want it on your nicely paved driveway.It won't be like gallons of the stuff,But enough to get the annoying smell of fuel on your hands for a while.Good luck you'll see it is very easy.
