As Due to the two mufflers, I think the gap between the engine and the firewall will be quite hot. To avoid some vapor-lock, I decide to install a shroud around the mechanical fuel pump. On the usual websites, this operation is considered difficult. It's not easy, but doable, the picture shows the black shroud. All will have to come of again, as I need to replace the gasket between the pump and the engine.



As I recently received all the sensors for the engine, it's time to begin their installation. First the oil temperature probe that gets bolted below the oil filter. It's the upper bolt in the picture with the white wire.



Then the CHT probes are installed. A small support clip is bolted to the cylinder head just below the lower spark plug. Then the probe is inserted and a quarter turn nut holds it tight. The picture shows the four probes and the four clips.



This is one of the probes in position.



Then the EGT probes. They are a bit more difficult to install as they have to be positionned on the exhaust between 2 and 8" from the cylinder on a straight portion. And distance has to be the same for all cylinders.



The picture shows cylinders 1 and 3 on the right side of the engine. The probes are at 2 1/4" from the cylinder. On the right side (cylinder 1) the pipe is not completely straight but moving the probe away from the cylinder poses some problems as you then run into the small bracket that hold the exhaust pipes together. For exemple putting the probe below the brackets on cylinder 3 (left in the picture), put the probe on the bracket on the other side of the engine.
The probes have also to be installed in a manner not to hamper maintenance.



On the other side, there is no problem with the chosen distance from the cylinder.



Then I install the fitting and hose for the manifold pressure. I will have to modify the fitting and install a restrictor to avoid fluctuation in the value read by the sensors.



This is the other end of the hose. I will also have to make some modifications as I need the manifold pressure for the instruments and for the electronic ignition.
