I'm not sure what type of sending units the original builder installed in my RV-8. My issue is that the left tank either indicates empty, or some level which appears to be an accurate based on visual inspection/time feeding from tank. There is a single wire that leads from *somewhere behind the tank* then into the fuselage. The right tank looks to be indicating properly. This has always been an issue with the plane since I've owned it, not something that just started. Questions:
How can I tell if this is a capacitance vs. resistive system?
What type of problem does this type of intermittent behavior indicate?
How should I test the system?
Thanks!
