What's wrong with 2/40 AC??

2 windows down, 40 MPH??

LMAO at the Dumb A**ed looks by the "Parts" people. Me: I ned points for a 289, Them: Hands me Chitty Pionts. Me: 289, 289, 289 ... Them: Ford made a 289?? (this was in the late '70s)

134 line isn't the same as hydraulic hose. Least it shouldnt be, nor should it be the asme as R-12 line.

From what I understand, 134 uses an ester based lubricant. Ester based lubes tear the crap out of normal seals and materials. At school there was a jar with Skydrol (ester based aircraft hydraulic fluid) and a "O" ring. The 1" ring had swelled to something like 3".

It would be my guess if a standard hose/ AC line were exposed to ester it may fail.

But then I have heard stories of people who have "converted" an R-12 system to R-134 and they claim they have had no problems. Mayhaps they havent had their systems exposed long enough.

It is my guess if you come up with the appropriate line and hose your friendly local hydraulic shop may be able to crimp them for you. Hell, Hell, they may even be able to hook you up with Ester resistant lines.

I though about using ye ole R-12... But I figure since I am going to have to fabricate lines I might as well save it for the Torino and go with the cheap stuff on the II... That and I have an R134 compressor already...

I remember someone telling me once why ester doesn't destroy the seals in a retrofitted system...but I can't remember... Had my Craprice retrofitted... It worked okay the 4 years I had it... Had to give it a little charge about the 3rd year but that was it..
