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.

The truck has 9000 actual miles on it now, but I fail to understand (1) why the windshield leaks and the vehicle has always been stored under a carport? (2) fuel gauge on front tank always shows empty when its full? (3) driver side exhaust manifold is cracked? Is there any recalls for this vehicle related to the above issues?
I was on my way home smelled gas coming from the truck. I have duel tanks on my truck. I just filled the front tank, and only went 10 miles and notice the tank was on little over half full. So I switch to the back tank and it was way over full and gas coming out of the filler tube. I have owned this truck from new and have never received a notice to bring in the truck for problems with the tanks running over. Ford did put out a fix for this problem by adding outside check valves to the tanks f3ta-9j274-aa, I could have been burned or blown up and my family. Thank god I found the problem before that happened.
