Re: Location for auxiliary temp gage sender

I would also think the one proper head location might have issues housing two sensors. Think others have used a tee but for only one large sensor. Not sure how well it works because of the problem O_D mentions. There's at least one way to do it with the flow in the heater hose as you have tried but would require a different location and some extra plumbing.

Since you have a 50, am going under the assumption you have the engine compartment heater with the thermostatically controlled heater valve. It should be possible to tee a complete second small loop with a restriction allowing just a minimal flow thru the tee containing the sensor -- barely enough to keep the sensor "current". The heater would still get the majority when needed. If that flow wasn't sufficient to keep the gauge correct and more would compromise the heater, there are heater control or diverter valves which bypass the full regular heater flow thru a second loop. If you were interested in either approach, perhaps that extra plumbing could be hidden under the heater box, fender or floor.
