Alright, guys, I have a '14 6.7L that will not accept fuel into the tank.

I thought the vent lines were plugged after reading up on some forums, in which blowing the air into the vent line brought fuel back up the fill neck.

I pulled the bed, removed the fill tube from the tank, and opened the flap with no pressure in the tank.

Moving on to the hardline that is welded onto the side of the neck towards the top and moves into a soft line attached to a plastic 90 on the tank, when I blow fuel into that, it immediately spits fuel back.

So, I'm stumped. Do gauge clusters play a role in anything?

The cluster did go out and hasn't been replaced yet?

So could that be an issue?

Open to suggestions.

Thanks in advance - Jordan
