One question.. does it read past the "Full" mark? Or does it move around a little? But... A common problem with the GM vans... There is a "Fuel Level Card" in the fuel pump located in the fuel tank.. The card send a signal to the ECM to the dashboard for your fuel gauge.. If you have over 100,000 miles on the van I would replace the whole fuel pump assembly (250 -300 bucks +labor) as the tank has to come out anyway.. remember Murphys law will come in if you just replace the fuel card.
What else can I help you with?

Ground the power wire and have someone watch the gauge. If it goes to full then the gauge is working. Clean the ground connection and turn the key on and if it reads then it is okay. If not then you have a bad sending unit.
