How did you get your fuel fill hose out?

[Water Rat]

GFS,

This may be a dumb idea but here goes, with the intent of breaking the bond between the hose and foam. Insert a round wood plug into the hose as close as possible to where the hose begins to be imbedded in the foam, then clamp a long pipe wrench over the hose/wood plug area and use torque/twisting of the hose to break the bond.

Hoping you find a method that works soon; good luck.
