I have a 2 k dually dodge with CTD and the freon valve started to leak on the hose from a/c pump to cab and I pulled out the freon valve and lost it and now I cant find a valve to replace it with, ******* /Dealer says I have to buy complete hose?( thats like buying a whole wheel and tire instead of vave core!) so does any one know who sells the core vavle (shrader valve)? I went to several parts stores and none of theirs fits my line, It larger than a tire valve core too! I even tried some replacement conversion cores too and they just wouldnt fit and thread in! I dont have my old one due to loosing it when I took it out! I hope someone can help or sell me one? thanks for reading this post!
