Fuel indicator, floating, on 415 C...

replace the floats. They will start sinking at some point and need replacing.

You left us hanging, Steve.

Did you get your problem sorted?

I got it; will call A&P in the am to confirm - The filled header was still full today; went around once and landed - measured gas in header and wing tank. Header was down, wing not. Went around again, a longer pattern, and header was down by a third of what it had before starting up today - wing tank not changed at all. My conclusion is that the pump is not feeding the header. Will run that by my A&P. It was an interesting feeling, to have the wing tanks full, and see the bead drop out of sight when descending...

Recently, the wire in the sight tube has gone to showing the tank to be partially empty - from about an inch low, to halfway down. This usually had been corrected with the engine running a moment or two, pumping fuel into the header tank. So - I filled the header, raising the float to its top position, but it rapidly fell to half way down. And I am not at ease with flying, not having any sort of honest indication. Does the cork get heavy after a few years? It has been at least 6 years, with no problem. Oh - also had a little fuel spraying out of the header; tightened the blades on the cap, and twisted the nut inside, to snug that on to the tube. Have I pinched the wire somehow? It moves easily with the cap off... Thanks, Steve
