Fresh air line to cold start injection
« on: March 24, 2020, 22:20:19 »
Stumped (again).  I am installing the air line to the injector on the intake manifold and I’m not sure about the routing.  Does it go above or below the throttle linkage along the firewall?  In the attached photo, I have it just resting on top (above) the linkage.

Thanks!

You may want to pay attention how far it is from the firewall. I had it 1-2cm from the firewall and I had it squeaking from time to time - took me a while to figure out the source of this noise. Then I just pushed it in deeper into the hose to FIP.

Thanks Pawel - I'll look at that.  (I hate a squeak.)  :)
