Fuel cut goes to the fuel decel plug... should be over on the driver fender unless it’s went w/ the HAC?
 
Well I swapped the lines around to match the diagram and plugged everything else. It appears the fuel cut off switch is still there, though I'll need to do some more research to see if the system is plugged in correctly and working. Still working on the shop regarding the HAC and my skid plate. Now starts the much debated debate as to other ignition parts like carb and dizzy, since I am learning more about how these work (and how at least my dizzy isn't actually original).

Hi All,
Is there an effective test to validate this valve at low altitude.
I see the suggested test in this thread, however, without being at altitude, how do you check if the diagram functions?

Also- does anyone have a HACv for sale?
Thanks!

The tests for all of the HAC system equipment are in the 2F Engine Emission Control Repair Manual. You can download a PDF copy from here on Mud, if you don't have it.
