TITTYSPRINKLING, TITTYSPRINKLES....So last night I picked up the EVAP canister/filter and put it on. Still does not work to put gas in. I went to Oreillys and pulled the codes. P0452 comes up as a EVAP system pressure sensor. P0463 is a fuel level sensor, which I figured due to my gas gauge not working. P0420 is a Catalyst system under level, this code has been on for a long time and I was told to not worry about it until I start to notice performance issues of the truck. Losing power and running rough. I guess I will pull the hose that goes from the EVAP canister to the vent valve I put on and hopefully that is plugged. What goes through this line? Air? Is the vent hose people have mentioned? The EVAP canister had 3 lines on it. This one to the vent valve and the 2 others looked to be the fuel lines?

My Ram takes fuel really slow if there is snow/ice and or dirt built up around the tank or fill tubes. Once you clean it off or thaw it out it fills fine again.
