I have a 2000 Dodge Durango with the 4.7L motor in it. The motor is a brand new performance motor. It barely has 2k miles on it. I keep getting this P0455 code which is large EVAP leak detected. I checked my vacuum lines and all seem to be fine. i also replaced my fuel cap. Any ideas?

 

Check the hoses under the truck going to the charcoal canister near the gas tank, under the drivers seat.

 

+1 on the charcoal canister hoses, also the one that runs directly under the black intake box its in a pretty hot location and rubber does not like being heated up constantly

 

Isn't that a contradiction?

 

Geez.... I gotta come in here and defend Dodges "baby motor" AGAIN!?!
