I just ordered a lube pressure test kit with the right nipple and a gauge. I also ordered the Kavlico oil sender to replace the one that came with the engine. The Dynon install manual recognizes the part number but it also said that they use a Kavlico sensor. I figure if they use it for the Dynon, it's probably what they actually have success with. I"ll check back with you in a few days when I get the parts. I hope after everything is up and running with a smooth pitch and a full RPM at static, that it starts to rain and hail with 40 degree crosswinds over my runway. Then and only then will I believe that I have arrived.
