Its been a while since I started replacing the vacuum lines on my 74 1.8.
So now that I'm back at it I'm wondering if I have the section from the air filter (upper part of throttle body?) to the Y then down to the Aux Air Regulator done correctly. Why is there a metal sleeve before the auxiliary air regulator? Why not one piece of hose from the Y down to the Regulator? When I look online at Peter Klager's layout, his diagram does not show that metal sleeve. Did a prior owner do this or is this correct from the factory?  |

If I'm not mistaken, there is a rubber elbow used there. 022.129.637 from the PET
 Or possibly 021.129.639 could be used  |

I have to admit of my blunder here. I have two elbows on the way from another forumite and totally forgot. Thats a little scary. Thanks. Steve |
