It is very odd! I can see a number of reasons why this isn't a good idea....Does the HP pump run when the flojet is injecting PS into the HP pump inlet manifold?The whole setup seems odd to me to start with... I don't really understand why I have a Flojet pumping presoak into the LP line at the pump, but I guess it does work.
I might settle for a CV, but It seems a bit hacky to me since it works fine, and I'm guessing its a precurser to a regulator failure or line restriction.
Thanks for the thoughts!
