ok, I've got a weird problem I've read a few posts relating to it but none seem to be exactly the same problem? I just purchased a 1994 f350 idi turbo and im getting an absurd amount of pressure in the rear tank. when I remove the fuel cap it expels a high volume of air and some diesel, I was driving it home and filled the rear tank and it pushed fuel out of the filler neck the pressure built up enuff that it blew an injector return line off and the fuel continued to come out of the return line even after the truck was turned off untill I undid the fuel cap and relieved the pressure in the tank what could possibly be the cause of this the front tank is empty so it can't be taking from one tank and returning to the other also the pressure builds up as soon as the truck is started no matter how much fuel is in the rear tank ? any help would be appreciated
