I'm looking for a sealant or kit to seal brass NPT inserts into a

Red high temperature silicon sealer. Local hardware store. Clean the
threads with alcohol and apply sealer. Lasts forever.
I'd check the label first. Last time I looked, it specifically excluded
use near gasoline.

The kinds I've seen will swell up & shed chunks into the fuel system.
