2004 F350 p0455 evap code problems

Good Afternoon
I just recently bought a 2004 f350 5.4L gas and not long after driving it it threw a p0455 evap code. Ever since then, the truck makes a loud drum noise every couple seconds at idle and it shakes the truck. it is also causing me to sputter when I am accelerating and it certainly not at full power. I have looked up many of the easy solutions and I replaced the fuel cap just in case and even the canister purge valve and no luck. From what I can see there is not an ounce of fuel leaking out of anywhere. The only thing I noticed is to small nicks in the two hoses coming off the top of the fuel pump, no fuel is leaking out. Any ideas?????

Welcome to FTE!

Sounds like maybe your charcoal canister is clogged.

Maybe your vent valve isn't operating? You should probably hook and and OBD scanner and do some live data., But here's a video for the Vent valve. Good luck.
