I cannot recall what I did, check my build thread. It works well for my needs with small hybrids.
Basically aside from a wornout, 30 year old, 15° pump will be an upgrade. My truck ran harder with stock 90cc sticks with an oversized HPOP than before. Documented the changes in pressures and duty cycle too I am pretty sure.
