Purge no nitrous?

[15psi88]

alright I just installed a dry kit in my buddys rx8, it seems to work well, but when we purge, no nitrous comes out, it seems to be all air, although the first time we purged it, it shot a nice cloud, after the first time we used it it wouldnt purge nitrous again I cant figure out why, but you guys are alot smarter than I am so could you please help me!?

I'm wondering the same thing, Could it be that the purge line is too small and restrictive? What diameter should the purge line be to get a good cloud of nitrous?

My purge line is 3 1/16th brake line I got from PepBoys, it shoots a good 6ft cloud when purged. Take the line off the bottle, make sure its off of course, and open the valve real quick and see if nitrous comes out or if its all air. If its all air don't get the bottle filled there again because they don't know what they are doing. When I get my bottles filled you can see the nitrous even when the bottle is very low.
