Replace front fuel pump, and have been using that tank exclusively as it starts and runs better than the rear. This morning I noticed fuel leaking from the rear tank, which was half full when I started using the front tank. I opened the filler neck and gas was spilling out. I turned the key to start position and the rear tank showed completely full. The return line from the front tank has been return unused fuel to the rear tank, causing it to overflow.

Consumer stated that her husband's truck was leaking gas from the front tank. They tried using only the bottom tank, but found that the front tank still filled up and leaked.

Fuel overfill out of gas cap of the rear tank. This is the problem on ford 1990 f150 safety recall. Ford extends the repair service to 150,000 miles. My ford is 155,000 miles. This is safety problem and ford should extend the service to cover more defective fuel pump.
Have been to ford dealer for two recalls, ignition and fuel regulator. No charge to me. Gas is still coming out of the filler neck of the tank "I am not using, I switch to that tank and gas comes out of the other tank--that I am not using. The dealer says this is not a recall and I need to pay for new fuel pumps in each tank. I don't understand that since the truck is getting gas fine, just to much and being returned to the wrong tank. Not being returned to the tank that is being used. I feel that this should be a recall and should not cost me $1000.00. Hope someone can help me.
