    General Fuel Pressure Regulator Question

    Do all fuel pressure regulators provide a rising rate of pressure based on the absence of vacuum/presence of boost?

    Only if its designed for rise with boost and there are different ratios. Most are 1:1 to keep the deferential pressure across the injector constant.

    Is it likely that most stock FPR's (on boosted engines) are not "rising rate"?

    Depends on the brand. Seadoo and Yamaha are not rising Polaris Weber is.

    I wish I would have put my gauge on before converting the regulator.
