[6pack] Electric fuel pump - PSI remember?

[richard olson]

Hi! 
I converter my mech. pump to a electric pump with 
Facet pump, Holley regulator, all the parts for DanMasters 
Handbook(page 167) and the blanking (Thank, Frank!). 
   
  How to put the regulator on so I am running a 1.5 - 2.0 psi?
   
  My regulator (Holley) has 3 outs - 2 are for carbs(?) and on from the the tank.
  Do I need one hose on a vacuum to I can see the psi?
   
  Thanks!
