For Rotax 912
These are good quality pressure/vacuum gauges. The printed instruction manual is only barely legible. I had to come back to this web page to download the PDF to get a usable copy. The PDF is in bad shape. It is a low quality noisy blurred scan of old documents. You might want to download it and make sure you can read and understand all of it before spending money on the kit. Aircraft Spruce does good work. This is a surprise.
Yes, this kit will work on any dual carb engine. Some of the adapters that are included will not be necessary, but it will work fine.
These are not oil filled. The kit includes 2 dampening valves that need to be used to get rid of vibrations.
