I am installing a fuel pressure gauge today. My problem is where you hook the sending unit to the fuel rail, I got a my fuel line for nitrous kit hooked to it already. Is there a adapter to where I can hook both my fuel line for the nitrous and the sending unit to.?

 

Yes their is. It's just a fitting. :cheers:

 

It is called a Tee fiting and most speed shops should be able to provide you with one.
