After close on 50 years I find myself continually re- evaluating sealants etc, what worked good a few years ago doesn't seem to be as good today, because a sealant has aviation approval doesn't mean its necessarily OK in a car environment, their (aviation) fuels etc are under much more strict controls than our mogas etc which has large variations in additives etc, seems to be case of finding what works for you today, but being prepared to change/search out a new alternative when it fails. With fuel lines rather than using sealants its safer to use a banjo or positive stop taper seat fitting or an o-ring/gasket washer fitting, even O-rings have problems with some of todays concotions.
