Assuming your talking about when you put fuel into the tank. Remember, an equal amount of air has to come out to allow the fuel to go in, so I'd say you don't have the tank vented properly.

So would I have to move the filler neck up or change the angle of it r raise the vent higher ?

Can't say exactly without seeing it but just imagine the flow. I would keep the filler neck as short as possible, definitely above the top level of the tank, and as strait as possible. You should have a vent hose that ran beside the larger filler hose originally. Is that still there?

I have 2013 3500 flatbed with exact same problem. It come from Colorado with bed welded to frame, very strong, but no taking off. Anyway it is such that the hose from cap to tank is at the incorrect angle because of the height of the flat bed, and only remedy would be goofy looking fuel neck or a higher flat bed which is useless as fish in bear fight. Or one could refabricate the fuel input system but I'm not one to mess with original manufacturer specifications. What you have to do is manually sit there and baby the fuel nozzle so that it barely comes out, then press it as hard as you can against the cap ( BUT MAKE SURE IT HAS THE LITTLE RUBBER RING TO SEAL IT) it works , trust me. It is much fun when outside ambient temperature is -25. Get your vodka gloves on HAHAHHAHAH.

I had the same problem on the wife's 2015 2500 after installing a flatbed. To make about 95% of the issue go away, I removed the metal tube and cut a section out to made it as straight as possible, I also incorporated a length of fuel rated hose in making the new modified fill tube.

Also, if you insert the fuel nozzle upside down, that usually helps.

Her truck is a gas burner (6.4 Hemi), but the issues are the same. One thing I had to do that you may not is relocate the ground wire to the nozzle opening (around the hose). This was necessary to guard against static electricity causing problems with gasoline when removing the nozzle.

Good Luck, RR
