I figured I'd throw my in. I know a retired Top Fuel Crew Chief and learned from him that he always "lapped" the fittings in the flare area.

After I learned about this I started inspecting mine and have found that very little surface area is actually making contact!

Try using some lapping compound (sparingly) on the flare, snug up the fitting and swivel it back and forth until it cleand the anodizing off of both flared ends of the fittings. Look for a nice pattern like you would find on a valve/seat face. Be sure to remove all the lapping compound with some brake clean especially important with oil lines!

Give it a try and if it is still weeping fuel go for a second round of lapping. I think this will take care of your issue and won't cost much. Other than my "Nominal Fee".
