did you create a vacuum in the system first? (I didn't which led to it's early demise I believe) I put on a different compressor, so the system was empty.
I used a kit from a parts store, but only one of the fittings was covered by the adapters in it, but luckily, it was the only one needed...
I just hooked onto the low side, and with the vehicle running/AC turned on to do the compressing, I opened up the vavle on the r134 charge/oil, and it sucked it in....
if yours isn't pulling in, you may have a bad hose someplace, and not creating enough vac pull....

a good thing to do also is replace ALL your O-rings with nitrile ones - (CHEAP at autozone) make sure to lube them prior to install
and I used the good ol' fashoned mineral oil, which is a better lubricant than ester, and what your system was designed for
pulling a good vacuum in the system before adding refrigerant is CRITICAL to system performance - maybe pay a shop to do that
you should also replace your reciever/dryer if you haven't already - it is supposed to absorb any moisture in the system, and gets saturated if the system is open for any length of time
I have had the system running for over 2 weeks now with NO problems. Last time, I tried R134a and it lasted 3 days!
