The two hoses above the glove box were NLA last I looked. That's good to know, I didn't realize you could just have the hose upgraded to barrier.

When I did mine only 1 was NLA but I got lucky and found a pair NIB on ebay & those are the ones I had upgraded. The other 3 hoses I bought in the normal course of things.

While all this was going on I actually spoke to Aeroquip who is the OE mfg and they gave me the specs on barrier vs non barrier hoses. They are rated in grams/hour/foot (or some other measurement) of hose. I believe the difference based on r134 was about 9X and those 2 hoses were leaking over their entire length.

How long did it take you to lose a charge with just those two? I replaced every hose except those but I haven't charged the system yet. Also, I do see that one is available, just not the other.

I was in Charlotte at the time and I had to top up the system in the spring then another 2-3x through the summer. I would notice a drop in performance within a week or 2 of a recharge.

Ill add (from my soapbox) that if you diy this and have a vacuum pump getting a micron gauge is mandatory for good results. Vacuum should be down to 500microns (1000 is too high) and your manifold shows 30" over about an inch of gauge face. Take one of those tiny hash marks an divide it by 25400 with your eye then tell me where 500 is :)
