I have a problem with my van. It has four tanks. One in the back and three down under. The one in the back is the last one in the fuel chain. It has a GFI internal solenoid valve. Can I turn the allen screw down in this tank, as it is completely empty, and isolate it when I fill the other three? This caused a big deal at the local Mobil Station in West Bend, WI 53095. Fire and Police shut half the station down for 6 hours on Monday afternoon. Please email me specific info for these valves as neither your web site or Ford has any clue!!!!
