93 f150 I6 8'bed with the auxillary tank. i replaced the rear tank as both tanks leaked . i was going to only use the rear tank but now the rear tank pumps into the front one. is there a check valve on the front tank supply line? i noticed that both tanks supply and return into a common fuel block so this is the only out come i can think of since i didnt touch the front tank or set up im guessing a check valve failed . any suggestions PLEASE

There was a Dealer installed check valve, part of an ongoing problem. If there is a fitting on the top of the tank that plugs onto the tank unit, then the fuel line plugs onto it, i have cleaned them out before , debris will stick them open.If you dont have the check valve,try Ford, but we havent been able to get them for a while now.If no valve, you will have to replace the fuel pump
