That is the coolant tube from the water pump. I needed something temporary to block the flow of coolant while I swapped manifolds and that was immediately handy as I had already disconnected everything and coolant was gushing out.
Bought the car with the CDSE's... Temp compensators removed/plugged, bypass disabled. Works as a 150CD, for the most part, aside from the dual choke....
Vacuum issues are solved but go as such:
When I put the manifolds back on a few years to run on my engine cart I just grabbed my spares. I didn't realize the intake was a 150CD and not CDSE (it has a slightly larger mating surface due to the notch cut in the gasket to accomodate the bypass valve). It worked fine for the firing cart as I only wanted to run it for a short time, so I didn't notice my error back then.
So strike one, both carbs had a vacuum leak of about 1 mm on the backside, nice and hidden. Then strike 2, both throttle shafts were worn and leaking.
Got the shafts taken care of and put on the correct manifold and it idles low now, instead of 2k+. No leaks
Just need time now to balance them with the unisyn.
I may later swap back to 150CD but I need needles and other bits to get my spares up to speed. What I have works, so it will do until then.
