Can anyone share an image of the routing of the PS CO2 test tube for an 85 /86, along with any helpful advise to installing it. The old one was long gone and capped, but now with a replacement in hand I cant figure out how these crazy bends line up.

thanks in advance

Look for the bolt holes at the back corner of the intake manifold (the parts that has 32V4C)

Thanks
yupp did that, which helps with the tubes exit. Still not clear how to route it around the block or header

Hello Greg,
Here's a couple of pics of the Passenger Side test pipe installed on my 85/86 School House engine. Let me know if this is what you're looking for. It is a bit of a challenge fitting it in. If I remember correctly, I believe the trick I used was to position it 180 degrees facing the opposite orientation in order to get the pipe threaded near it's final destination. Then, when close, maneuver it so it was correctly oriented 180 degrees back in order to thread into the exhaust manifold. Hope this helps - it takes a bit of patience.
