Leaking Durajet carburator on 79 C10

If it where mine, remove the carb filter and seal up the threads so you don't need to put any further wear & tear on the carb threads. Put an inline filter in the rubber hose by the fuel pump.
Gas resistant sealant I've used successfully. Might take some hunting to find a local parts store that has it: https://www.permatex.com/products/ga...-liquid-16-oz/

And if you do plumbing, you might have some rectorseal it is gasoline rated and you can find it at home despot. I have not used it on any gasoline apps, but its the goto for other materials. Take your pick;
