Since I am new to this kPa thing I worked on conversion to values that make sense to me. Please check and let me know if this look right.
kPa table
kPa psi manifold
pressure
300 43.5 28.8
249 36.1 21.4
210 30.5 15.8
170 24.7 10.0
140 20.3 5.6
115 16.7 2.0
100 14.5 -0.2 VAC
90 13.1 -1.7 -3.4
80 11.6 -3.1 -6.3
70 10.2 -4.6 -9.3
62 9.0 -5.7 -11.6
44 6.4 -8.3 -16.9
37 5.4 -9.3 -19.0
30 4.4 -10.4 -21.1
20 2.9 -11.8 -24.0
