Need help with cat air line.
Howdy all! This is my first post on F150 forum but I have been involved in Powerstoke forums for many years. I recently purchase a new to me 1995 4x4, with the 302. The PO cut off the second cat when he installed a new exhaust system. It sounds great but unfortunately I need a cat to pass inspection and emissions. I ordered the magnaflow cat that replaces the two originals with one (the second) cat with the air tube. My question is, where does the air tube on the second cat go? Currently the first tube going to the first cat is still there (coming from the air pump control valve) but I don't know where the second one should have originated. It appears when I install my new magnaflow cat set up, I'll only be utilizing the second air line (that I currently can't locate). I hope to install it this weekend so any help is GREATLY appreciated! Thanks in advance!

I am also new to the site, but here is what I have done. I have a 1989 Ford 302. I recently replaced my cat system with a walker system. New y pipe and only one cat. My system came with an extension tube to go to the existing air valve pipe. I was told before I bought the system that my old system did not have two cats. It had a cat and a resonater. I would think yours would be similar and should have the one pipe for you to connect to.

That is exactly what I have. I received some misinformation about a "second air line" that does not exist! I'll most likely be extending the one air tube just like you did. Thank you for taking the time to reply!
