Honestly if you have a pump you can just pull a vacuum on it and it'll dry it out like new. In a near-vacuum moisture just can't hang on, even to the desiccant in there. Point taken that they're cheap insurance though.
I have a couple of questions if someone could address them:
- Would an AC shop need to pull apart under my dash, or in the heater core area that would require pulling a fender? I have brand new paint. It looks like the inboard section of the underhood HVAC box comes off. But are all the parts in there?
- When I buy a new pump and dryer from LMC, as I did, it has some oil in it. Would that be the old style or new? I poured it out but did not flush it.
Just a reminder - this thread is (or was supposed to be) about converting factory air, not replacing it with aftermarket serpentine chrome modern pumps or Vintage air.
