The contact owns a 1996 Ford f150. The contact stated the vehicle has a duel gasoline tank. When the back tank is selected it will pump gasoline to the engine, but it will also pump gasoline into the front tank and pressurize the gasoline, forcing it out of the filler neck and cap. When the vehicle is parked gasoline overflows onto the ground, and when driving the vehicle, the gasoline spills out along the highway. When the cap is removed from the tank, a larger amount of gasoline will spill out, and the gasoline is filled up to the filler neck. The consumer has to watch the amount of gasoline that is in the back tank to ensure that the overflow will not occur. The service dealer said that the check valve had to be replaced. The check valve prevented the gasoline from going from the back tank into the front tank. The manufacturer said they would not cover the cost for the repair. Updated 01/04/06.

Fuel leaks from the front tank vent cap down the vehicle side to the ground. Occurs regularly when both tanks are filled and rear tank is used first. Have to switch between tanks frequently to keep contents from overflowing. This is a known problem. Not enough people dead yet? recall it.

Fuel is transfering to front tank when using rear tank causing fuel overflow onto ground and poor idling when front tank gets pressurized.

When switching to front tank it started to build pressure, and gas pour out of rear tank filler spout. Please provide any further information.

While fueling rear tank front tank started to overflow. Vehicle has not been taken to dealership.

93 v 125 000/fuel tank assembly: a portion of unused fuel from one tank to be returned to second tank. When it occurred the second tank exceeded, causing fuel spillages. Spill can result in a fire when exposed to a source of ignition. Dealer/manufacturer were notified, and informed consumer that vehicle was not covered under recall.

Problem lies with back fuel tank; when it pumps fuel to front tank there is too much pressure, fuel drips to ground. Also had to replace cracked torque converter.

When pumping fuel into one of dual fuel tanks, one tank overflows into another tank that's already full, causing a fuel spillage.

Fuel was moving from 1 tank to the other, causing spillage. Recall was issued & taken care of by the original owner. Manufacturer would not acknowledge repairing the problem for the second time. Consumer purchased the kit pertaining to the recall & put part on & had a repair shop to do the rest.

Fuel from the rear tank flows into the front tank, through the fuel system.

The truck is equipped with dual fuel tanks. When both tanks are filled and the rear tank is selected it pumps gas into the already full front tank, causing it to run out of the fuel cap down the side of the truck onto the ground. I feel this could easily cause a fire yet have been unable to get the Ford dealer to repair this problem. I have not been able to use the rear tank for over two years. Is this a common problem with dual tank Ford trucks?.
