In the process of rigging this engine and notice there is no fitting at the top rear of the block for my analog gauge.I do notice one at the bottom rear that hooks up to a psi sensor that I assume is for the smartcraft gauge.Now,there is one more of these sensors on the drivers side that has nothing hooked to it.What is this one used for and how can I keep the smartcraft connection and still use my analog gauge..Thanks Robbie
Robbie:
The one on the STB side (down below the starter) is the Digital Pitot (speed) Sensor.
The one mounted at the rear (with GRAY tubing) is the Water Pressure Sensor. As it came from the factory, there was a "tee" right below the PORT SIDE fuel rail, with gray tubing running forward (and a plug in the adapter end of the tube). This may have been removed previously.
Tee's, adapters, etc. are readily available to allow you to "tap in" to this water pressure circuit. Contact our Parts Department for details.
