Kavlico fuel pressure sensor capacitor
Tried to get all the good search arguments in the title! Two weeks ago installed the Kavlico sensor to replace the original, which was beginning to give flaky readings. Worked fine for a couple of weeks. Then yesterday the needle was jumping between zero and max reading, with frantic high fuel pressure alarms going off. Searched the forum, read about the necessity for placing a 330 mf capacitor across the sensor output and ground. Installed the cap today after confirming with Dynon tech support. Actually installed a 470 mf as that is what they had at the Radio Shack Aviation Store. Problem solved!
My recommendation to anyone replacing the sensor with the Kavlico unit - save yourself double work, install the capacitor from the get-go.
