[DeTomaso] Speaking of EFI--Water Temp Sensor Question

[JFFR]

Your EFI system water temperature sensor is mostly used to get the 
system to switch from open loop operation (cold start) to closed loop 
operation (normal operating temperature or somewhere just below that). 
If you are still using the original swirl tank/fill tank system, you 
could put the EFI temperature sending unit in the tank and use the water 
port in the front of the engine block for you water temperature gauge. 
You could also use a thermostat housing from a 429/460 Ford engine, 
which had a port for some type on emissions control sender. That of 
course would require you to cut and modify the original Pantera engine 
water outlet pipe. Using any available port on the water pump will give 
you false low water temperature readings.

My EFI water temperature sensor is located in the water jacket of one of 
the cylinder heads. I have CHI 3V heads, but the heads had to be drilled 
and tapped for the water outlets because I used a Fontana block, so 
drilling a couple of more holes in the cylinder heads was not a big deal 
at that point, but can understand if you don't want to do it.
