Hi Alberto,

I have found that the fuel pump pressure can range from about 7 psi to well over 30 psi.
I would not be concerned about the pressure for tuning purposes, in fact it makes no difference
what pressure your pump is putting out as long as it is pumping and not allowing air bubbles to
enter the fuel line.

Set the inital setting of the regulator flush with the body and needle valve about 2.5 to 3 turns out.

The starting point for the Dingo pump is screw flush with the housing.
