Ok, started installing a TNT F1 system. I've mounted the bottle and run the lines. Before I start connecting things I have one question. Which fittings need loctite / teflon paste and which don't? Thanks in advance!

 

I'd do it to all of them man its not gonna hurt them and its easy to do

 

AN fittings DO NOT use any sealant. Only use it on the NTP connections, and for those, use limited quantities.
In other words, if it hooks up to a nitrous line, no sealant.
If it going into the noid, then use a small amount. (You will see what I mean, if NPTside is flat while AN is flared.)

 

dont wanna use teflon tape either...one little piece of tape breaks away it will get stuck in your noid and than your screwed!! so be carefull.
