I guess I'd be afraid of putting Permatex thread sealant on a brass fitting I wanted to get loose in a tight spot, in the field.

Even the old stick pipe dope does not say "sealant", it is to smoothe things out till they get tight.

Years ago I had a contractor putting 2" pipe in a pipe rack for an air distribution system. He had inexperienced hands and they were cutting threads too deep. With the threads too deep, the thread bottoms out in the fitting and won't make up. They kept trying to put pipe dope on to seal until we found out what was happening and made them unscrew 3,000 ft of pipe and cut the extra thread off so the fittings would make up right.

Tapered threads seal just fine with a little light oil as lubricant and if they don't seal something is wrong.

A Farmall fuel line is certainly low pressure, some of my in-line filters even get by without a clamp, but if a tapered thread joint is seeping it is not made up right.
