I have to wonder ....
A Ramforum member was told that a Roll Over Valve in the Fuel Tank could cause a back up in Air Pressure Relief.
That Air can't get out, so gas can't go in, except as a trickle.
Also the Roll over valve could not be RESET or Replaced.
Does that mean fuel tripped the Roll Over Valve & that tank is worthless, except for dirty scrap ??
I would have to believe that there is a way to reset the Tip or Roll Over Valve.
A shade tree mechanic friend, used to Trip a friend of his, Tip Over Valve that was in a El Camino.
He would wait until the El Camino's Owner went inside, then he would take the side of his fist & strike the El Camino's sheet metal, right next to the Fuel Filler Door.
That tripped something that caused the Fuel Pump to malfunction, he waited for the owner would come out & try to drive away.
My friend would then go under the hood & make like he was trying to fix the problem.
After a short period of time, he would do what ever he needed to do to reset the Malfunction, it had to be an electric fix to reset it.
I know our Rams are much newer & they have a different technology, but i would think there would have to be a way to reset the Roll Over Valve
