Boost referenced Fuel Flow Control Valve  #1062 

This is the heart and soul of a boosted mechanical system.

This valve begins  at wide open and is controlled by  a 10 lb pressure valve coming from the Flow Control Valve  going back to the tank- This will hold a large TURBO  pill–  The 10  lb keeps it from flowing fuel while the fuel pump is trying to initially get fuel to the nozzles.  After it idles, the pump makes  around 5-10  lbs, so it opens that valve and fuel rushes to the tank. Since boost is non existent or very low  yet, there is no need for much fuel flow. This Fuel Control  fuel valve  is controlled by boost, from your air valve  so more boost causes it to close, less boost keeps it open longer. When boost climbs, it  will close at a pace that keeps up with fueling needs. The ratio of operation of this valve  is controlled by The Air  pill holder which you put inline from your boost source and send it to the -6 fitting on the Flow valve. 

We usually don't use a spring in the Air Valve  that is holding the boost pill, but some customers want the boost air valve  to open around 5 lbs of boost 

The LARGER the pill – the more boost it will apply thus closing the valve sooner.

The SMALLER the pill, the longer the valve will allow fuel to go to the tank causing leaner conditions which work with less boost. So Big pill for Big boost, small pill for smaller boost.
