Very quickly I will post what I think is the answers to a couple of questions.
I have been dealing with not being able to fill my tank with out the pump cutting off after a few seconds for over a year. The problem is caused by the rollover valve not allowing air to vent therefore the gas backs up in the filler neck.
My truck is a 2014 1500 base model, but alll are the same. Ram/FCA knows about the problem but refuses to correct it.
I decided if I replace the tank, mine was 26 gallon, I would replace it with a 32 gallon.
Good news, it worked. No parts to change save the vapor line from the Charcoal cannister to the line from the purge valve on the engine. I reused the line from my old tank and routed it over the top of longer 32 gallon tank and connected it to the same line on the chassis.
If you open the wire loom to get some slack you can lower the tank low enough to work on the connections (fuel line and electrical) which are a bear to disconnect.
I had exactly 3 gallons in my old tank and new tank was empty so that was a snap.
You can change the tank volume with ALPHA OBD to 119 liters to give you correct rang info on your instrument panel, but the fuel guage will be accurate because the tank is the same in the area of where the pumps sits.
Sorry no pictures, I am 72 years old and my accomplice was 73. Rain clouds were looming. We did it in 2 hours on the ground with the left rear tire on a ramp using a motorcycle jack to raise and lower the tank.
I almost cried tears of joy when I was able to put the pump handle in my tank and let it pump with the lock on the pump handle.
