fuel filter replacement... relieving fuel
the fuel filter looks like an easy job, i've disconnected the fuel pump, took out the efi 15AMP fuse, cranked up the motor, and yet, there is still fuel dripping out of the fuel line when I loosened one end of the fuel line. One thing to note, when i cranked up the motor, shouldn't it be running until it's used up whatever fuel's left and then it should die? when i disconnected the fuel pump harness and took out the fuse, the motor cranks, but won't turn over. let me know if im doing this correct as i don't want to waste a lot fuel doing this job. thanks!

i just pulled in the garage, waited for the engine to cool down, and then i pulled the ful lines off. i just propped the lines UPWARD resting agains the intake manifold so that way fuel wasnt constantly dripping out...
but in reality, no matter what you do, or how you do it, fuel still will drip out. its no biggie

Yeah....manual says it should run itself dry, but it's the PRESSURE RELIEF process you're interested in, not burning the fuel up. So you're going to get some fuel drip - you're trying to avoid a pressure washer effect when you pull the line!
I'd be inclined to crank it a little more than 1x, myself. But I doubt it's much more than a soda bottle worth of pressure (?).
Make sure that exhaust is cold! Be safe.

REMOVE THE FUEL FILLER CAP.
On a warm day, enough pressure can build up in the tank from vapors to almost empty the tank when you pull the filter.
Don't worry about pulling the EFI fuse to stall out the engine. At best, you'll reduce the pressure in the line from 55psi to, oh, 40psi. But the pressurized volume of the line is small, and you won't lose an excessive amount of fuel from that.
As stated you will lose some fuel, so think ahead. Get a container to catch it. Wear Nitrile, not latex, gloves. Leave the garage door open for air, no matter how cold it is. And don't use that nice drop light; if you bump it and break the bulb, we'll never even hear about it.
