Re: Releiving fuel pressure (SJLJ)
You are going to loose a small amount of fuel when you change the filter. Anything you do to releive the pressure is not worth the small amount of fuel that run out when making the change.

Re: Releiving fuel pressure (SJLJ)
I would be prepared for some fuel coming out.
I just did my fuel pump and ran the car dry
and there was still plenty of gas under pressure
in the feed line, so don't assume and keep your face
away from where you could get sprayed...
I've seen someone get gas in the eyes before..
ouch... HTH

> With the engine running pull your fuel pump fuse until the car stalls. Remove your gas cap and let it sit over night if you can.
Correct, also relieve the pressure from the fuel rail valve. It is on the passenger side. Use a rag to catch the small amount of fuel that bursts out from the valve.

Re: Releiving fuel pressure (SJLJ)
Yup! Even if you relieve the pressure on the fuel rail, the second you crack open the fitting on the fuel filter, the gas will start to siphon out of the tank. Relieving the pressure keeps fuel from spraying out all over the place but won't keep the fuel from siphoning out of the tank. If you left the line disconnected it would probably drain your entire tank.
