How is the desired fuel pressure obtained with the Filter King? Is there a dial or something to set it at the pressure you want?

Take off the acorn nut, loosen the lock nut, turn the screw to adjust (1/2 turn at a time, according to the instructions), tighten the lock nut, replace the acorn nut. There's a port to mount a pressure gauge.
