I have a p/n 0-80770 Avenger carb and use the Holley blue street/strip fuel pump. Using the regulator that came with the blue pump I cannot get fuel pressure regulated. Screwed all the way down, pressure is 13lb and with adjustment screw all the way up pressure is 11lb's. I only need 5 to 7 lbs. Any suggestions from anyone???

Fuel system debris probably found it's way into the diaphragm and now it can't seal as well (regulate).
If this is a return style regulator, make sure there isn't a restriction in the return line, back to the tank.May God's grace bless you in the Lord Jesus Christ.
