-AN fitting/line sizing?

Turns out I have a nice big hole in my nitrous feed line so I need to order another one. To get the size, would I just measure the orifice of the fitting it attaches to? It's 3/16 so that would make it a -3 line. Just wanna make sure 'cause I'm trying to get it here for tomorrow night.

3 an ?? kinda smallish aint it? Sure it aint 4 an?
Is that the ID on the hose, or the fitting? Should be measuring the fitting I would think. Most are 4 an stuff on nitrous I've seen.

How long has it been there??

I measured the orifice that's on the fitting that the line attaches to, 3/16. That would be a -3, correct?

they have a shop right by me that does nitrous setups. just bring it to them ad let them take care of it. they can make ANYTHING. and awesome quality too

oh and they fill nitrous bottles too. get yours topped off while your there

Is that the place you told me before, Melville?

yep

Well I just ordered a -4 from Jeg's since they said they hadn't heard of a -3 feed line before. :shrug: If that's not it, guess I'll be off to Melville after work tomorrow.

Sounds like an oddball size to me.
But yeah 3/16 should be 3 an.
I dont believe I've ever seen 3 an feed line before.

Shoulda got new fittings and some 6 an line !
and a pro-shot solenoid. Good for a bunch more juice than the cheater solenoids will carry.
I havent sprayed the new motor yet, but its all in there just in case I get a wild hair.

-3 is pretty small for a feed line. i have seen the -4 feed lines, i have -6 to the solenoid, then -4 from there to the nozzle. that could be why some can run a .125 jet, or it could be an undersized solenoid. not all flow equally.
