I'm new to this forum and have been building an Acroduster Too for a long time. I am installing the instruments and engine controls. Right now I am planning to install a capacitance probe into my main tank. It is an 'inverted' tank so there is a baffle 14" from the top. There is 6" under the baffle. How do I measure all of the fuel? Can the probe be passed through the baffle in order to get to the bottom? A hole would need to be drilled through the baffle. What are some of your thoughts out there. How are the rest of you measuring all of your fuel?I posted this question on the Starduster boards a couple of days ago and haven't had one response. Maybe everyone is on vacation!!RonEdited by: Ronboone
