Water/Methanol injection check valves

[KenH]

I am curious if anyone has added check valves to the Roe water/methanol lines at the injectors to try to improve tip in detonation performance by preventing water from being pulled from the lines during vacuum conditions. Seems to make sense logically, but also seems like they would partially defeat the progressive injection control due to having a crack pressure of 16-22PSI.

Any experience or opinions on this topic?

no, the pump in in the way and should not allow any substancial amount to be pulled during vacuum.
