Does anyone know what the 1/8" barbed fitting is for on the regulator itself. It is nowhere in the instruction sheet they sent with it. [img]/ubbthreads/images/graemlins/shrug.gif[/img]
You don't need to hook it to anything. Just set the pressure where you want it and that is where it will stay. If you where working on a forced induction gas motor then you would use it to raise fuel pressure with boost.

If it's the pressure reference port that he is talking about it is for boost. There is another port though for if the diaphragm fails I just assumed the instructions told him what it was for. The instructions probably don't mention the boost port because it goes unused.
