BENDIX AIR DRYER AD-4

[belfert]

My bus uses a steel armored line from the compressor to dryer.  As far as I am aware the Series 60 doesn't use any air to operate so I don't have other air lines in the engine compartment.

My bus is now 15 years old.  It uses the new nylon air line and push fittings in a number of applications with no issues I am aware of.  It seems to last a long time.
