I moved the engine back on some saw horses and started to install the firewall items. I did one thing on the engine and that was install the VA-128 restrictor fitting that will be used to get the oil pressure. They use a restrictor fitting so that if one of the lines breaks you get a small leak instead of very large one. The line is only used to sense the oil pressure so volume is not a factor.
I drilled the mounting holes for the sensor manifold, this manifold will get oil and fuel lines (I am using 2 of the 3 ports) the sensor screws into one port and then via a wire will send the pressure information to the EFIS. I had to slot the holes in the sensor manifold slightly; the holes I drilled were a tad wider than the holes in the manifold.
Next I drilled and mounted the manifold pressure sensor supplied with my Dynon EFIS/EMS; a line comes off the #3 cylinder to a port I still have to make or buy then a tube will connect to the Dynon manifold sensor. I will also âTâ off this line because each P-Mag also needs manifold pressure lines.
Sensor manifold, the line there is for oil pressure
Manifold pressure sensor, you can see hose connection barb.
Restrictor fitting which sends oil to the pressure sensor.
