So i just bought my Vette last Thursday and it came with a nitrous kit on it. I filled the bottle and *though I programmed the window switch right. Anyway I left it last night with pressure still in the nitrous line to the motor (so the gauge was at 750psi) and this morning it was at 0? I know the bottle was closed but does that mean I have leak?

 

Does the kit have a blowdown tube? Although 750psi wouldnt be enough to pop a disc make sure the burst disc didn't rupture.

It's possible you have a leak around the bottle valve. Fill it up and open the bottle and listen around. If it's leaking that much it's usually pretty easy to hear.

 

if you can, just get it filled up with compressed air, no sense in wasting nitrous if you have a leak. drop it in a bicket of water and look for bubbles.

 

mine does the same thing...after you close the bottle it will have pressure for 4-5 hours...the line itsnt completely leak proof...and all the fittings....as long as when you close the bottle it doesnt shoot to zero quickly your fine

 

Sorry, I am really new where would the blowdown tube be?

 

On the bottle, it would be a tube coming off the bottle and exiting outside of the car.

 

mine does the same thing so i took soap and water and checked all the fittings and found no leaks. I asked on another board and they said it just does it and no one knew y. I think it comes out the purge alittle but i don't know. mine takes about 6 t0 8 hours before the line is empty.

 

Well I remember that so I don't come one here complaining about leaks in the future....
