    Air cleaner, what is this tube for?

    None of the pictures of 3x2 air cleaners have this tube coming out the bottom on the right side. What is it for? Thanks

    I'll jump in. Test me you guys. I've been learning a lot about 427/435's lately.... , well on a 67 that is. However my C3 knowledge is marginal. Your icon is 68-69.

    By the appearance of the pipes coming from the exhaust manifold, I think it's for K19 A.I.R? Either that or for the flame arrestor? Is that a Winters aluminum head? yes.....A L71 with the L89 add-on?

      Rich is correct, the tube is for a 67 with A.I.R.. It was not used in 68 or 69.

        It is a L89 car but what is K19 AIR?. I thought AIR had an air filter on the pump(???)

          Here's the sheet from the AIM....Air Injection Reactor Equipment......of which I really know not much about other than in the books.

          edit....actually, I'm familiar with A.I.R. in 70's Jags. They used the GM pump. I rebuilt one a few(10) years ago.

            Starting in 68 A.I.R systems had the air filter (centrifugal fan) on the pump. In 66 and 67 the A.I.R pump took it's clean air from the air filter base and a hose connected the base to the pump. This is what you are seeing.

              Are you certain? I don't see this in any 63-67 catalogs I have on hand either. In the 1969 Stingray Guidebook it talks about there being two BB pumps one with a vent on top (but these are described as being for L88/ZL1.

                The 66 and 67 A.I.R systems are very different from the later ones.

                In 67 since the A.I.R system was only required on cars sold in California and an option everywhere else, it is pretty rare. Since there is very small market for such parts, little if any of it is being reproduced and therefore sold through the catalogs.

                Attached is a picture of a 67 tri-power with A.I.R and a 68 to compare.

                  As others have mentioned, you have an air cleaner base for a 1967 L-68 or L-71 with K-19. The correct base for 1968-69 L-68 or L-71 would not have the tube.

                    There should be a tube on the drivers side of the air cleaner base beside the rear carb going to the drivers side valve cover, the tube on the air cleaner should face downward, useing a moulded hose.

                      Thanks everyone. Hopefully I can find a way to trade this one for the correct one. Another mystery solved!

                        Mike, the rarity of the base you have should make trading very easy

                          I'll trade you a nice driver '59(in my avatar), for the whole engine, wrong air cleaner base and all!

                              actually I was wondering what the guarantee would have to cover.
