I understand the fuel pressure safety solinode but what i dont get is why there is a fuel line going to the nozzle along with the No2 line??

can someone explain this to me please???

thanks Jerry

 

That would be for a wet shot of nitrous. In a normal dry shot, you have just the nitrous at the nozzle. But in a wet shot, you introduce fuel with the nitrous in the intake through the nozzle. On the larger shots of nitrous, it is safer to run a wet shot because the motor's fuel system wont put out enough fuel and it will lean out. A wet shot also makes more power, IMO.

 

Since using nitrous, which has oxygen molecules, is basically chemical forced induction of more oxygen, the fuel line going to the solenoid allows you to also inject the correct amount of fuel to go with the nitrous.

This is known as a "wet" kit because it also has fuel, and is much safer to use than a "dry" kit, which injects only nitrous and not the corresponding amount of fuel.
