N.B.
THE MEASUREMENT MAY BE FALSIFIED BY
THE INCORRECT NUMBER OF REVS OR BY
THE WRONG POSITION OF THE TUBE.. IN

REDUCED FUEL FLOW RATE. THE SUCTION
OUTLET ON THE MANIFOLD HAS A SECTION
INTENTIONALLY REDUCED FOR THE PUR-
POSE OF ENHANCING THE SUCTION PULSA-
TION AND THEREBY GUARANTEE A CON-
STANT TAP FLOW RATE.
