Ok, so here it is...2000 VDP S/C, I had recently replaced the fuel pumps from a failure. So I figured it best to change the fuel filter in case there were any discharge from the defunct pump, even though the tank was spotless.
I have changed this before so it isn't new to me. I back the car onto ramps, shut it off, pull the fuel pump fuses (actually all the brown ones) and start the car to bleed off the fuel pressure. The car runs to a stall, I shut it down, pull the key, pop the filler cap to remove pressure and proceed to the task at hand.
When I remove the line it bleeds fuel (lite pressure, but flowing), I expected some to be still there, but this didn't bleed to a trickle, it kept coming. So what should have been a simple filter replacement has turned into a 15 minute episode of getting gas all over me as I frantically replaced the filter.
When I replaced the pumps prior, I rewired everything to spec, I had taken pictures to be sure I had redone it the same.
So, with the job now done, what could have caused the fuel cell/pumps to still have pressure? Any insight would be appreciated.

 

Why would you run the car? Just crack the line/cap loose it bleeds the pressure off and continue. From my experience i think the level of the gas tank plays a role is how much/If fuel will continue to flow. Replacing the filter in my XJR with a very low tank nothing came out, replacing the filter in a 98 xk8 with a full tank i took a little gas shower as it ran down my arms (burns in the armpits). remember the pumps are at the Very bottom of the tank so any fuel in the tank exerts pressure on the pumps.

 

its called gravity and syphoning

I can agree with the gravity statement if I had this same issue with my Expedition or Corvette. As with all pumps they are at the bottom of the tank, it would be kinda tough to get all the fuel otherwise. I've replaced the pumps on all 3 of mine at some point. I run the lines somewhat dry so I don't get the backflow from the line going to the engine which has no back check valve and keeps me from wearing any more fuel than I have to. I was working off ramps on a sloped driveway. Just cracking the lines doesn't do it, they are seated in the filter and have to be pulled out and 2000 VDP filter isn't in the most assessable position behind the axle and truss.
My concern is I may have a bad pump which is allowing the fuel to flow, unless when I didn't put the fuse back in after the burn off that it allowed the pump to freewheel?
