Purge kit
bottle heater
Bottle gauge
Blow down tube

What else do we need to complete this?
We are in Germany and can't always get parts fast or run to auto zone saturday night to get something. Any input would be appreciated.

We can't access your shopping cart. Does he want any kind of safety switch? Like if the fuel pressure or oil pressure drops it shuts off the nitrous. The rest looks like all that my buddy had.
