Have also made some holes for the coolant temp sensors (gauge on left of photo, ECU on right)
and the manifold air temp sensor in the runner at the back (on the early Delcos its more for direct charge temp than intake air like later MAF based systems)
More problems with blue fittings - this time it was too small in diameter (advertised at 5/8" which is roughly 16mm, was more like 14.5mm!) and too long to be able to screw it in where I wanted it. Problem and solution:
Merged together
and fitted to the manifold. This will supply the heater core (which also acts as the bypass), and there will be no additional hose off the thermostat housing - see photo in previous post.
