I found an old TSB. Did you ever have any recalls done on the van? Because there is one to replace the filler neck assy.

Subject: Safety Recall #665 -- Fuel Filler Tube Rollover Valve and Ground Strap
1996 Model Year Dodge Caravan and Grand Caravan; Plymouth Voyager and Grand Voyager; and Chrysler Town & Country Minivans (NS) Built Through:
• August 9, 1995 (MDH 080910) at the St. Louis Assembly Plant (‘B' in 11th VIN Position)
• August 10, 1995 (MDH 081018) at the Windsor Assembly Plant (‘R' in 11th VIN Position)
The fuel tank rollover valve on the above listed vehicles, may allow liquid fuel to pass into the vapor canister under certain circumstances. Also, an electro-static charge may build up on the filler tube and cause a spark when refueling. Either of these conditions create the potential for a vehicle fire. To correct these conditions, the fuel tank filler tube must be replaced with a filler tube which incorporates a third rollover valve and a ground strap. Also, the fuel tank vent hoses must be rerouted.
