5v regulator only works the gas and temp gauges in a Clipper but is fed from the instrument cluster fuse. Oil light should also be fed via the same path from the instrument cluster fuse as the BAT light. It gets ground thru the oil sender which is just a normally closed pressure switch that opens above a certain pressure to extinguish the light.
Temp sender should be in the same place on the Hash engine -- rear of left head next to firewall. The heads are reversible so with the manifold on front end the rear end of heads is about the only place there is an accessible water port. I believe it is the same on Hash engines with the left used for temp sender and right for heater water. As far as I know the Hash engines all were equipped with Ultramatics but even if not should have the same port linkage bracket or closures bolted to the end of the heads to cover the open ports.
The temp sender has a wider resistance range overall but should have the working area at the same approx 70 to 10 ohms as the fuel sender with the 70 ohm end being at cooler and 10 at hot.
Here is a bit showing the actual sender resistance range another poster found using a 52 temp gauge as the display but the same basic sender 55-6 uses. Since the gauges are marked differently you would need to take that into account when correlating the approximate temps between gauges.
