The joke is on me .. I began to remove the defective gauge so I could put the new gauge in that Bob sent. Took the sensor loose at the manifold, took the gauge loose at the dash and pulled on the tube. Oooops! The water gauge tube ran to the
oil pan .. the
oil temp tube was in the manifold
Swapped them and they both work fine .. sorry Stewart Warner!
There were two of us building .. one working under the car and one on top. Got our wires crossed
My fault .. the dash was wired by me and I shoulda double checked ...
Bob, I'll be returning your new gauge unmolested
