Is the airline it simply soldered to the ferrule...otherwise I don't see how the airline can be made air tight? Thanks

If your question relates to how the ferrule seals to the tubing: When the nut on the tubing is tightened into the fitting that is on the part being connected, the ferrule is compressed tightly around the tubing to form an air and liquid seal. If this doesn't answer your question, restate your concern and ask again.

that is exactly my concern...the gas gauge post thread appears to be NPS 18 and the nut NPT so I can't see the cone fitting that sets in the threaded post collapsing enough to seal the air line that is a pass through, but maybe you are right! When the weather clears I'll give it a bumpy ride to see what transpires. Thanks for the help This message was edited by MICHV8 on 10-5-23 @ 6:40 AM

So your asking about the hydrostatic air line fittings? The air line is soldered to the cone type fitting and the nut (same thread as the sender or the hex tank on the rear of the gauge) compresses the cone into the female fittings. The cone and nut usually distort the female fitting making it difficult to reassemble but the thread is not NPT.

Before I ran the airline, I slide all 14 feet of it into 1/8 ID plastic tubing which prevented any kinking and protects the air line. I also created a thin gasket for the gas cap (which I never knew was spring loaded). I soldered the air line to the cone fitting (I mistakenly called it a ferrule) and tightened it down with the nut. Lo and behold, the gas gauge works! Thanks for the help!
