This is the low pressure side, fitting is closest to the battery side of the line. They leaked on both of my Tours. Stop leak stopped the leak and I add some oil to the system to replace the lost lube. They also leaked a little where the hose is crimped to the line on the compressor. Cheap BadYear hoses. Furd really had some great quality control!

Only other problem I had with the A/C is a bad compressor clutch relay. It acted like low pressure problem; contacts were shot. 40 amp relay only costs 9 bucks.

Ford seems to be out of them a lot according to local parts guy and Bill in Vegas. Same relay used for R window defogger and starter relay.
