AC Hoses

Absolutely. I haven't had any luck finding a shop local to me that can do ac lines.

Does anyone know if the 89 suction line is compatible with the 88?

AC guy here, if you have the other end of your cut hose you can braze them back together with map gas and some silfos... Aluminum is the most difficult alloy to braze but it is doable by an experienced brazer. Aluminum brazes between 800-900 degrees but becomes liquidous just after 900 making it a very narrow window... I would definitely flush everything out if its been left open to atmosphere, you can use a rx11 flush kit that is all in one, one time use, so that you don't need to buy any specialty tools or fittings. I assume youll need to go to a shop to get the system evaced unless you have a vacuum pump and the gauges to use it. Youll want to hit sub 500 microns for a good pull, if you can't pull below 700 you either have a leak or a LOT of moisture in your system. Leaving moisture in there with the refrigerant will create an acid that eats away all your seals and what not. Make sure you replace all the seals before going to 134a, otherwise same thing the 134 mixing with the older refrigerant will eat the seals. Nitrogen is the best gas to use for flushing and pressure testing, its inert and dry, it absorbs moisture and helps remove it every time you do a fill and release IE a "purge". I triple purge every used system just to make sure we get all moisture removed. I would probably remove the accumulator and make sure its 100% empty also, along with flushing it out with the rx11 flush kit to make sure non of the oil is left behind. Someone else already listed how much to put in, I would have to check the AC tag under the hood to confirm if that's correct or not but assuming you still have the AC tag just double check it before filling. Remember to NEVER break your vacuum with atmosphere, it needs to be broken by releasing the refrigerant into the system or you will suck in moisture.
