Hello. I have a 1997 Dodge Ram 2500 Cummins diesel 4x4 long box. The small piece of tubing from the air intake manifold to the AFC housing (boost pressure signal) is rotten and not repairable. Right now I can't get boost over 10psi. I've looked online but I can't seem to find the tubing/fittings for sale anywhere. Would anyone have links to a site where I can purchase these? If not...can these be replaced with regular air tubing and compression fittings? If "YES" could someone please tell me the threads present on both the air intake manifold and the AFC housing air fittings. Also I noticed that the fitting for the AFC housing has a very small open hole....does it matter if it's replaced with a regular opening fitting? Thanking in advance for any assistance given. Brian.
