What I mean is, with that siphon tube in their, does it matter if the label faces up, down, left, right or does it matter what direction the valve points - towards the front of the car, back, down, up, etc . . . you get the point
thanks guys

 

Yes It dose, If its not positioned correctly you will not be able to use all the N2O in the bottle.

All the bottles i've used, are suppose to be label side up, Valve points toward front of car.

 

I'd empty the bottle and take the valve off to verify the siphon tube position. Especically if this is a new install or you are having surging problems. The bottle needs to be mounted with at least a 10 degree angle from horizontal and preferrably with he low point behind the high point for when you are accelerating.

 

Got it right with the low end and high end. Also I was told to have the valve opening pointing down. JP

 

yea with the valve opening down and the label up
