rdauphinais Posted March 18, 2018 Share Posted March 18, 2018 (edited) Working on the air brakes on a 89 cs300p, full air system, and had leak under the cab so I found the leak at a aluminum manifold, one of the fittings had rusted and started leaking. So I took the block out and in the process, I snapped 3 out of the 5 fittings on this thing. Looks like all the hose on this truck is 12mm ? Where do I get fittings and can someone tell me what that aluminum manifold piece is called?
