On a positive note, your r134a only cost $6.40 a can before tax. One thing I forgot to mention is to make sure the fittings on your gauge are not leaking. My el cheepo Harbor Freight gauge had a leak on the high side that kept me from being able to get a good vacuum. It would be a good idea to inspect your fittings where the gauge connects to the compressor to ensure you don't hear any hissing noises coming from there as well. I corrected the leak on my gauge by replacing the o rings with some spares I had left over from my $5 o ring kit from O'Reillys.Quote:

You shouldn't have to use two o-rings...look it over real well to see what's up with that.
...you mentioned using the fittings to press the orifice tube in IIRC, did that give you any trouble or seem hard to tighten at all?
If you don't get, say, 10-15 hg within a few seconds, you have a leak.
Hang in there!
Maybe the wrong size O-ring was supplied with the hose. It's possible. The next time I am at the auto parts store I will look for an R-134 O-ring kit. Supposedly they contain all of the O-rings you need and then some. But as of right now, I am in no hurry. I just cleaned up the garage and closed everything.Quote:

Well, when you get back to it...Quote:

Awe man. Don't quit. I was just joking.
Do you still have your old accumulator? I would flush it, install it, and see if you can pull vacuum with it.
Farrar, I think you have already compromised the A/C by not having the 90 degree fitting and moving hoses around to compensate. I think you should take a break and get the fitting from Hervey so you can put it together like I showed in that pic I gave you. You shouldn't need 2 o-rings, that sounds like trouble. You could also try filling with nitrogen, then you could possibly feel the gas escaping and find the leak that way. Just a few ideas.
If you can't find the leak, just put a can of R134a on your charge gauge and only open the valve a little. That should give you time to hear or spray soapy water around the system. The fittings don't need much force since they are o-ring sealed. You should use a little refrigerant oil on the o-rings when you assemble them.
How little should I use? Some of them were put on nearly dry, but I did not have a lot of oil handy, and I could not remember which type was safe for R-134 so I figured better safe than black deathy.Quote:
