So I have a pinhole leak in my AC high pressure line that runs from the condenser to the firewall. Looking online to purchase one but the part number listed (92440AT05A) shows a downward tube at the end near the firewall. However mine does not have that tube and in the service manual I have it does not show it. Can't find the correct pressure line anywhere. Am I going to have to take it off and go the the Dealer to get one. Any thoughts or comments?
