<VV> Fuel pump pressure

[corvairduval at cox.net]

I would like to hear of any ""Look how many "high pressure' problems have
been cured by making the pressure a little higher"" situations that have
actually happened, with gauge readings.

Well yeah, Clark was correct ... each time material is removed from the
spring's length, its stiffness is increased..  So, the more the spring is
cut, the more the pressure increases.  And the point beyond that was that
if the spring is not held captive the fuel pressure will fall to ZERO when
at the point when the spring is at full length.  One might get away with a
little of that around town ... not on the highway.

In our racing days we had springs wound to our specifications as a regular
practice.  Today because most of Detroit has been redued to ashes,, I am
not sure I could get it done today.  But fuel pump pressure is not as
critical as some believe!  Look how many "high pressure' problems have been
cured by making the pressure a little higher.
