I have had this model of fuel probe in all three tanks of my KR from day 1, which is now over 14 years of flying. They work great when they are working and give good stable and accurate information. However, I have had cronic problems with the grounding wire that wraps around the base of the probe inside the tank. The wire is attached to the probe with a pop rivet, but there is a problem with the wire and the probe being dissimilar metals, so even in the dry climate here in NM, it gets some galvanic corrosion due to the dissimilar metals, which allows the ground on the probe to float. That causes intermittent low fuel readings, then the gauge eventually quits. I have replaced all three probes on my plane at least once and have had repeat problems with some of them. I'm sure others will write in and tell you they have never had a problem with theirs. My experience with using these for 14 years and 850+ hours is OK, but not as good as I would have expected for something with no moving parts. It seems that I get roughly 5 years of service before I have to remove the wings so I can pull these probes out for maintenance. That is not satisfactory IMHO, but your mileage may vary. :o)
My recommendation would be to look into the heavier capacitance fuel probes used by Vans in their aircraft. -Jeff Scott Los Alamos, NM ----- Original Message ----- At 08:04 PM 7/19/2011, you wrote: ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ http://www.aircraftspruce.com/catalog/eppages/skysportfuelsys.php These are the ones I have. Mine are 7 feet long and run the length of the outer wing panel, low at the root, high at the tip. I think the price has gone up a bit since I purchased mine. Larry Flesner fles...@frontier.com
