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
have the same problem?
