Large tubing is low side. Small tubing is high. You have a shop manual? If not, download them free at MyMopar. No I don't work there. Some of those manuals got there because of some of the guys on here
Attempting to charge an AC system with a dimestore low side hose is no way to run a railroad
Thank you for that shop manual link, I'm heading there now. You are right about the dimestore...either the red or blue both ends do not fit on high or low on the engine.
