Bubbles in header tank visual fuel gauge

Skyport is Vernon Gregory. Currently Vernon’s wife is in the hospital and Vernon is not taking orders. You can probably take that cap off and reseal it with some sort of fuel proof sealer. Hopefully Vernon will let us know when he’s back on line.

Bubbling fuel in a Rain Pruf gauge is almost always the result of a leaking red cap on top or the gasket between the sight tube and the cap. Both parts can be easily obtained from Skyport. The red caps will crack and you won't even notice it, but the fuel will bubble up. The glass tube is easy to clean and you can easily overhaul the gauge by disassembling, cleaning, then reassembling with a new cap and a new gasket.
