Question For The IAs: Fuel Lines

[43-29080]

Am installing a new set of Univair fuel lines in the L-4, tank to LaTour gascolator, and gascolator to Stromberg NAS-3A1 carb. Fittings on the ends of the lines are steel, which mate up to brass connectors. What's permissable and desirable for these connections? Teflon tape, EZ Turn lubricant, or does one just tighen them down until they're leak free?

Thanks!
