Your drawing says "Needs 1150 cc/min flow". That is from full tank to reserve in just over 10 minutes.
Where does that value come from?


I calculated the flow of the solenoid converted petcock to be approximately 1300 cc/min.
I'm going to do a more accurate measurement on the next one that I'm converting now.

P.K.

Just a remnant of another engine on the dyno.-NEGLECT

my calculation is
.6 lbs/hp-hr
65hp
.73 gr/cc
=414 cc/min
on reserve with 1/4 tank of head


Petcock total fuel flow is
550 cc/min actual average, but...
Petcock bowl acts like a fuel splitter to 3 outlets.
They do not flow the same-at the same time, but they do average out
