New vs Old - Oil Pressure Sender

Hi John,

There is no 100% answer for you. There are many Rotax engines that use a VDO sender and with Dynon and some of the others they use a Kavlico electronic one or the VDO. Either works. So it's up to you. A remote mount to the firewall is a good idea because it helps reduce the unwanted vibration. Plumbing shouldn't a big issue. It's just a fitting that goes into the oil pump housing where the sender went and then a hose in fire sleeve to the firewall where you want to mount the sender. Then a fitting on the end of the hose for the sender to screw into. Really pretty easy and cheap.

Do anyone know the specific part number of the Kavlico oil pressure sender that has 1/8 NPT threads that attaches directly to the oil pump housing? I am confused by the part numbers that Kavlico uses and want the part that has wires coming out of it.

Mouser seems to only have a 100 PSI unit with a  3-pin socket of unknown specification.

Is the 100PSI sender appropriate for the Rotax 912?

I want to avoid extra tubing in my very tight cowling.

Thank you ,

Will
