For those who didn't see the earlier posts, there was confusion as to the sensing location of the oil sender. It senses the pressure right after the pump and in some (instrument) setups, this can show-up as pressure fluctuations on the gauge during normal running. The lower sensing location - just underneath the electric sender - is at the end of the oil gallery supplying the bearings. Between those two points (despite being close together) are the oil cooler, the oil filter and the pressure relief valve. If you want to sense the oil pressure at the lower point, you will notice a pressure difference of some 50kPa lower (7 psi) than the standard position, but the lower position gives a steadier reading and reflects the pressure supplied to the bearings before the oil returns to the case. I've asked Jabiru to amend the drawings of the respective oil circuit schematics in the manuals to make this clearer.

I'm very interested to hear what Jabiru's take is on this.

All are new and still in the original boxes. If interested email me direct at jimmieblackwell@austin.rr.com or call me at 512 695-6627. Each instrument has the appropriate connectors, panel attaching hardware, sensors and senders. Following are the instruments: Dual oil temperature and pressure by Westberg, includes sensors and sendors. Cylinder Head temperature by Westberg, includes sendor. Fuel level by Westberg. Air Path Compass Airspeed indicator, 0-120mph, by Airwolf Altimeter Prefer to sell them altogether. To buy them from Spruce and Air Wolf would cost over $800. I will take $500 for all them and I will pay for shipping. Thank you.
