The regulator body has a 1/8” NPT to accommodate your fuel pressure gage. In addition, there is a brass barb fitting 
with an O-Ring seal that can be used to change the fuel pressure for applications that uses boost pressure through the 
carburetor. 
Your regulator is preset to 7 P.S.I. which is our recommend operating pressure. Deviating from this pressure can 
create a number of operation problems with the carburetor float control system. If it becomes necessary to change 
the fuel pressure it can be adjusted by loosening the lock nut, and turning the adjustment stem with an Allen 
Wrench. To raise the fuel pressure turn the stem counter-clockwise. To lower the pressure, turn the stem clockwise.  
After adjusting, tighten the locknut to prevent the adjustment stem from moving.
