Im removing my nitrous system that was on when i bought the car. they have a stainless line coming off the driver side fuel rail to the solenoid. When I remove that, what should I cap it with? If so, a link or name of what I should use would be great. Will fuel be spilling out when i take the line off?

Also, what does a used kit go for these days?

I read about people just using a tire valve stem cover....Or do i need to replace something "inside" also?
Thanks!

 

Install a shrader valve in the end of the tube and then a valve stem cap. Then shoot who ever did that install...

 

Lol. Why do you say that?
