Three stars for the system application not the gauge itself. Rotax recently replaced the 1/8-27 NPT oil pressure gauge outlet port bung with an M10 metric thread on their 912 engines. The tubing kit sold here (and everywhere else to be fair) for VDO gauges includes only NPT fittings. If you buy a VDO mechanical oil gauge and the tubing kit you’ll also need to source an NPT-metric adapter for the engine connection that works with the tubing kit. I could not and now have a plastic tubing kit I can’t use and instead will install braided steel oil lines.
