<VV> Fuel pump pressure

[kenpepke at juno.com]

Right you are, Clark … A spring is a spring.  Removing material increases the pounds / inch rate.  As long as the spring is captured in a manor such as the frame / moveable lower control arm or pump cap and moveable diaphragm … it will resist its compression by exerting force at its given rate on both ends.  If one cuts the fuel pressure spring short enough it will no longer be held in compression and the force exerted will be reduced to zero as will the fuel pressure.
