I was working on my Jeep late last night and every once and a while the evap was farting, I don't know how else to describe it lol. Then after a while it just went to sounding like someone slowly letting the air out of a balloon. I understand the tank is equalizing from being hot earlier in the day but in all my years I never heard anything like it before. There is no battery in it at the moment I just got the replacement engine installed in it last week and I put 5 gallons of gas in it to give it a test run. The entire Jeep was disassembled at one point and is basically all put back together now, It almost sounds like a pinched line or something but nothing I could see. I shook the purge valve around a bit and it stopped momentarily but started back up. Can they be taken apart and cleaned? I something sticking?
