	Advance Auto, or Autozone.  For my VW Autozone had the condenser
	and the dryer (special order on the dryer).

	You really don't have to prime the lines, but you should replace
	any oil lost when your lines blew.  That could be an oz or two.
	I'd probably be conservative and add 3 oz.

	Some service manuals give guidance on the amount of oil to
	add per component.  You could also take to total system
	charge of oil, and adjust it for the component damaged, and
	a factor of whether the leak was slow or fast.

	You can buy 8oz of oil for $3-5 from your parts place.

	Then have them give you a little oil from their bulk.

	Having them do the evac is OK, but see if they'll leave the vacuum
	on for a period of time so that the water has a chance to boil
	off, and so that any leaks can be detected as a loss in vac.

	You might consider gauges ($55), tank 30# of 134 $120? 90?,
	a vacuum pump that runs on compressed air $15 from Harbor Freight.
	You can also use an old refrig compressor as your vac pump.  Just
	leave the oil in the compressor when you cut it off the refrig.

	If you still have questions, drop me an email, and give me
	a phone and time to call.
