[MangoMike]

Bruce,

I'll check my Marathon tonight to see if I have one.

Hi Mike,

I think I have figured this out, at least for now. The air Dryer/filter Speedaire 2Z328B appears to be inline with the Aux Air Compressor. The air passes through this filter and then to the Norgren filter up against the aft wall of the lower steer bay. The Speedaire filter system is no longer made. I have found 2 new ones online and ordered both, will have them in the am tomorrow. I think that they had installed 2 systems on this bus. 1 Norgren F74G in the steer bay and one SpeedAire just inside the front bumper on the right. Anyway I will replace the defective Speedaire unit, (the entire unit) and keep one as a backup. Thanks for your help with this, I would be curious to see you and others have this type of install on their Marathon's
