Fuel Tank Return?????
Hey guys i need help! My '94 7.3L is going through fuel like crazy on the front tank. But not the rear tank?? So last night i filled up both tanks and this morning on the way to work (which is only 24km's) i burned up 1/8 of a tank. When i got to work i decided to add a bottle of Howes additive. I opened up the rear tank and fuel started to pour out on the ground????? 
Is the tank selector switch not working properly or what??? Any help would be greatly appreciated!! Thanks!

Sounds like the FSV is not closing correctly on switch over..... when you switch tanks does the FSV make a ZZIIPP noise... Does the fuel guage switch tanks, as it is the last thing to complete. Gas or diesel FSVs from 88-98 will work if your a wrecker diver.
