Finally found the right bypass air hose.

Oh yeah, one more thing: When I went to install it, I noticed that there was a slight ridge about halfway up the circular mounting base that the hose slides over on the underside of the air cleaner. This ridge isn't parallel to the base, but curves upward slightly. After struggling a bit to get the new duct onto the bottom of the air cleaner, I finally figured it out. This ridge curves upward slightly so that you can thread the duct onto the mounting surface, instead of just pushing it on. Once I started "threading" instead of "pushing", it went on easily and looked great. Yeah, I know - probably TMI (too much information).
