Hello I ordered a blue Holley fuel pump and regulator, I’m just a little confused on how to set it up and where do I put the pressure gauge on the regulator?

 

If this is for a Nikki, the regulator should be a 12-804 (low pressure version). There is one inlet and two outlets on the regulator. The inlet is of course where the fuel comes in from the fuel pump. One of the outlets goes to the carb and the other can have a pressure gauge attached. The inlet and outlets should be marked on the regulator. For a Nikki, set the pressure at 2-1/4 to 2-1/2 psi.

 

this is for a Holley 600cfm carburetor

 

This is what I ordered

 

I got it all set up I’m just trying to figure out how I can mount this fuel pump
