“Gas leaking from fuel filler pipe onto inside of wheel well and ground. Examination reveals design of pipe assembly (metal pipe inside corrugated plastic tube), traps condensation and water around metal pipe guaranteeing rust and leaks.

NHTSA complaint #10413568, filed 2011-07, 51,459 miles“When the vehicle fuel tank is filled, gas fumes are detected and some fuel can be seen on the bottom of the tank (a few drops of fuel). As the tank contents lower the smell and leak goes away. An access hole on the side of the van reveals that the tank has a small leak where the plastic fill neck was bonded to the tank. The steel fill neck and rubber connection look fine. This is a conversion van w/o a left hand door. This vehicle was bought from a southern climate area and is only recently been brought to a northern climate so corrosion is not suspected. …”
