Fuel Filter replacement method
It seems pretty straight forward. Unbolt it, R&R. My question relates to how to relieve the pressure in the line. I read online that you should unplug the fuel pump fuse and let the car run til it stops? That sounds like it would do more harm than good. Any input?
Edit: It's an 88.

I know from experience that that won't work on my 96'. With the fuel pump not operating the engine won't run.
There is a Schroeder type valve by the fuel rails that you can use to relieve the pressure.

That valve would make quite a mess, right?

Let the car sit for a while before changing the filter. The pressure will bleed off. On the other end, I disconnect the larger of the two lines coming out of the tank. Some people pinch the rubber hose. I've changed filters before with fuel running down my arms onto my trouble light (old incandescent). I'm surprised I'm still around.

As noted, disconnect the supply line to prevent fuel continuing to siphon out while the filter is off which it will do because tank is higher than filter
Have rags to mop up the fuel contained in the lines which will run out

Man, what a sloppy mess this R&R can be. There are a few threads on this. Do a search. I pulled the fuse and ran it dry, crimped the feed and return lines from the tank and pulled the bitch out from the top. That's prolly the easiest method. The trick is to keep the fuel from coating you.

Changed one in an '89. Did it in the morning before driving. Placed a pan under the work area. No bleeding a fuel line or pinching. Loosened the outgoing line bolt first and put a finger of a disposable glove over that line. Then disconnected the incoming line bolt and quickly removed the old filter and put the new one inplace connecting the incoming line first. Then reconnected the other line and fully tightened both end bolts... done. Lost maybe 4 ounces of gas. Why make this a more complicated procedure than it needs to be?

I took an old filter and used the fittings to make caps for the lines when the filter is off. Actually, you mostly need it on the supply line to the tank, finger tight is good enough for the short time you need it.
I cut the fittings off the old filter, cleaned them thoroughly, cleaned them again thoroughly, blew them out with air, and plugged the cut ends with some polyurethane mastic adhesive I had lying around. You could use any kind of goop that resists gasoline.
Also, the standard strategy of waiting until the tank is ≤ ¼ full helps greatly to avoid a dangerous mess.

Got it done! Thanks for all the tips and help.
I ended up just taking off the gas cap and that seemed to help. I pretty much had a full tank, too. Lost maybe a cup full. Took me about 40 minutes because I couldn't find metric wrenches in my FIL's garage.
