This is to clarify where some of the components are, and how to adjust your pump..
Below Pictured is the non turbo no altitude compensating pump
The major difference between this, and the turbo/altitude compensating pumps is the addition of the "LDA" on top as pictured below
The most common asked question is usually about turning the fuel up or down.. Adjusting the smoke screw so to speak.. This adjustment is pictured below.. If your pump has never been tampered with there will be a steel collar crimped over the threads.. Remove that collar by some manner and loosen the 10mm jamb nut.. Best method on the car is trial and error, typically a quarter turn at a time.. When you get close you may need to use eighth of a turn increments.. But this can vary pump to pump pending on wear and such..
Turning the screw clockwise increases the fuel injected over the entire rpm range.. Turning the screw counter clock wise reduces the fuel.. Keep in mind that when increasing the fuel you may need to decrease the idle, and when decreasing the fuel you may need to increase the idle..
Idle adjustment is pictured below, it's the screw closest the engine.. The screw that is further away from the engine is the max RPM adjusting screw.. Both of these adjustments are pretty self explanatory.
