the accumulator has a built in (welded in) "dryer" that contains desiccant. Everytime you crack the system open it is a good idea to replace the accumulator to absorb/keep moisture out of the system. You should be able to find an accumulator between ~ $30 - $60 for your application. Install the dryer then pull a vacuum on the system if it holds move on to charging the system.

I assume this is a retrofit 134 situation. Doesn't sound like you want to invest in the entire kit from NAPA, since you have already done a good bit of work. However, it might be worth the investment in an orifice tube that NAPA sells just for this situation. It allows more flow at idle and slower engine speeds, so that you don't roast in slow traffic. I don't remember the part number, but it was in stock when I bought mine.

Stop by Harbor Freight Tools and get their A/C orifice tube removal tool. It'll save you a lot of time 'cuz it's a straight ***** trying to coax that sucker out with a pair of needle-nosed pliers.
