Fuel pump pressure has a direct impact on engine performance as it regulates fuel delivery and combustion efficiency. Most vehicles from the factory were de signed to operate at an optimal fuel pump pressure between 30-60psi. If the pressure goes out of this range, it will result in many operation problems to an engine. For example, when the fuel pressure falls out of specification, less to no fuel is given access to which retards engine acceleration and output. Around 30% of engine performance problems are attributed to insufficient fuel pump pressure (Automotive Service Association, ReportJune2022).
High Pressure High pressure is good for the appropriate air-fuel mixture maintenance. For example, if the pressure is too low it may cause your engine to operate overly lean leading to misfires and diminished fuel economy. Conversely, excessive fuel pressure curtails the creation of a lean mixture which would present lower emissions and better MPG. The Journal of Automotive Technology published data from a 2021 study that confirmed even small pressure drops in fuel can cost you as much as fifteen percent in engine performance.
Two of those are rough idling and hard starting, but the other one is poor fuel mileage; things that let a manufacturer know they need to replace your Fuel Pump Pressure Regulator. For example, from a 2020 case study report: Defective fuel pump contributed to approximately a 20% reduction in average fleetwide MPG performance for commercial vehicles during one operational season which led to increased operating expenses.
According to automotive expert Emily Johnson, "Proper fuel pump pressure is crucial for the performance of your engine. Off the charts might considerably influence power and efficacy of car. In high-performance engines, this is especially important since precise fuel delivery isn't just desirable; it's required.
