Race pump regulator

[Moparornocar51]

HI guys i have a race pump regulator like this

http://www.racepumps.com/Regulators-Street.html

There is a vacuum port i installed it to the carb!

At idle i have around 6 psi now i run them fuel pump too...

When i pull the gas the fuel pressure goes down to around 3 psi, now i was confused and checked all my fuel lines, tank ect...

but then i read somewhere in the net that this is normally when u have that vacuum port and they say i should adjust more pressure at idle and when i pull the gas the gauge will drop to 6-7psi

So now my Question is, should i disconnect that line and i also didnt really understand for what it is?

Thanks for help Peter

Yes disconnect it. You would use it on a blower motor.
