Thanks. I have ordered enough DEL seals for every fitting in the airplane.
I think you pegged it. I did not know you were supposed to oil the flare
tool. That's gotta be it. Here's hoping the DEL seals work as advertised.

You are supposed to oil the flaring tool to give the smooth surface needed.
You can use Fuel Lube to plug up small leaks. The Dell seal are commonly
used on fuel nozzle hose connections which have a very high working
pressure, over 500 PSI.
