Important Notes

• A rapid fuel pressure drop after the pump shuts off is normal for aftermarket regulators of any brand and is not a defect; pressure resets immediately when the pump is activated again. Long cranking or slow pressure build while cranking points elsewhere, typically to feed hose drain-back from an internal pump module leak or a missing pump check valve
• Use a wicking medium-strength threadlocker when installing the vacuum fitting
