Avanti R2 EFI - Coolant Temp Sensor

[Tim G]

I've been thinking for a while about adding EFI to my 64 R2 and I think I've found a good system from Fitech:  The Go EFI 4 Power Adder.

One required part of the install is a coolant temp sensor that is 3/8" NPT.  I haven't taken the bracketry for the ignition shielding off the engine to get to the coolant sender on the back of the driver's side head...Is it 3/8"?  If not, any other ideas where I could install this sensor?

Thanks,

Tim

I drilled and tapped a spot on the water manifold. There is a bleed petcock that I removed and placed it there.

Brad - That's a nice clean place to put it, and accessible too.  Thanks for the idea!

Does anyone know if the right head also has a threaded port for a sending unit that I could use to add the temp sensor for the EFI?

The stock sending unit is mounted to a plate that bolts to the head. There is a blank plate on the passenger side. There is no reason whatsoever that you couldn't put one on the passenger side also.
