Recessed fuel drain install

Changing to recessed fuel drains. Manual says loctite type thread sealant. Anyone use thread tape as well or just the thread sealant?

I never use tape on fuel or hydraulic systems.

No, no tape!

Not to pile on, but, , , , , , NPT fittings and tape are not a marriage made in heaven - by the very nature of the thread design. Thread sealant is the way to go.

Never use anything to seal fuel system components that can plug your fuel system.

Years ago, I had a wizzened old A&P tell me to get some stuff called Fuel Lube.I bought a small can of the stuff that will last a lifetime and use it for thread sealant and such. Has out performed anything else I tried and i am sold on it. Its the consistency of peanut butter and never gets hard and is fuel resistant. I checked aircraft spruce by searching for fuel lube but all that came up is a product called "EZ Turn lubricant " which it says is the functional equivalent of Fuel Lube. Bruce N199CL
