Air Dryer issue

[Curt Sprenger]

I paid $133.81 for the parts to rebuild the AD-2 air dryer...check &
purge valve maint. Kits, desiccant cartridge and new (not rebuilt) air
governor. Shop charged 3 hours labor. I asked the shop about the AD-9
and they said it is a lengthy job as the air lines will need to be
reworked for that unit.
