I use the green natural gas stuff.. The white stuff works too even then becarefull not to get it inside the tube, jet, solenoid, or line. I've seens peiople cake some much of that stuff on I thought it was being used to hold the stuff together.

Teflon tape and pipe dope are not sealers, All they do is lubricate the threads so you can thread more in.

What you might wanna do is full put the entire kit together off the car, take note how deep the fittings go into each other. Then use a sealent or tape as far back away from the start of the threads as possible.

A friend of mine had tape freeze, and get lodged holdint the solenoid open. Once we got the car pulled over and the hood popped it had frozen the throttle body and 1/2 of an ls1 manifold.

Just so you know, all AN lines should NOT have any type of sealant on them. The seal is at the flare, not the threads. The only thing you should have pipe sealer or teflon on is NPT threads... and even then, its not safe to use because it can clog whatever line you are sealing. Use sealer sparringly and dont over do it. Too much and it will goop into your line.

And like said, test fit the NPT threaded connections, then use the paste sparingly.

did you use hard brake line? or a flexible line? i would prefer to have something flexible so i can easily route it up to my cowl panel or something.

thanks!

AND can anyone recommend what RPM i should have my window switch shut the nitrous off at? i was thinking 5800 or 5900 since i put my rev limiter at 6,000. ?

5800 is what i would do. you do not wanna hit the limit while its still spraying cause it will cut fuel/throttle then by by motor... and u have a lil room to shift.

when i had spray on stock motor and rev limit at 6k i used 5800. u should be fine.

but im no expert.

when my kit was on the dakota, i had it set for 5500 with a 6000 limit, and used hard line, but, i already had it laying around. will probly do the same on the mustang when i install it on there...
