Spent $280 on a lift pump delete, wish I had done it sooner
My truck kept losing prime after sitting overnight, so I swapped the factory CP3 lift pump for a regulated return setup. The kit cost $280 and took a Saturday to install, but now fuel pressure sits rock solid at 15 psi even after a week parked. Anyone else seen a big jump in cold start hesitation after going the regulated return route?

Cold start hesitation usually traces back to air getting in somewhere, not the pump itself. Check your return line fittings and the fuel filter head, a tiny seep will let air in overnight even with good pressure once running. Pressure gauge won't show that since it only reads while the pump is spinning.
