I am wondering how to fill my nitrous bottle when I disconnect the nano. It seems that the hose that I take off will have a hole for the n2o to come out while it is being filled. I have not gone to do this yet but can someone with this set up set me straight. It has to be something simple and I am just being a moron.

 

there is a check valve that stays on the valve. it comes with the nano kit.

 

I guess I will have to look at it. I need to fill up the nitrous tomorrow.

 

The part that is in the bottle is the check valve. When it comes with the kit it has black sealant applied to it, should be on the end of the hose, or in the little bag when you open the kit.
