What’s the Difference Between Fuel Pump Grades?

Generally, the difference in quality of Fuel Pump grades is usually a matter of factors such as quality, durability, flow rate, and pressure capabilities. High-quality fuel pumps are purportedly designed to offer an improved level of performance and durability, especially under harsh driving conditions. For example, a standard Fuel Pump normally provides fuel pressure from 30 to 80 psi, which would be appropriate for everyday driving, while performance-grade pumps are capable of handling higher pressures over 100 psi to support high-performance or modified engines.
One important way in which Fuel Pump grades differ is in their flow rate, usually measured in LPH. The standard-grade pump may pump about 150 to 250 LPH, mostly sufficient for most factory vehicles. On the contrary, a high-performance Fuel Pump may pump over 400 LPH, which is necessary for engines needing more fuel-for instance, turbocharged or supercharged vehicles. The greater flow rate ensures that enough fuel is fed into the engine, especially in states of high acceleration or load.

Fuel Pumps are also different in durability and quality. High-grade pumps are usually manufactured from more robust materials that are resistant to wear and corrosion, enabling their normal lifecycle to extend upwards of 100,000 to 200,000 miles. As opposed to this, the low-grade and aftermarket pumps are cheaper; they will not give the same kind of reliability and long life. It is at this point that this becomes really important for trucks, SUVs, and performance vehicles, which place higher demands on their fuel system.

This is attributed to, for instance, the 2019 Subaru recall of more than 500,000 of its vehicles because of the use of low-grade Fuel Pumps that were causing stalling and poor performance in the engines. The event showed the importance of the right grade for performance and reliability.

As Henry Ford, one of the pioneers in the automobile world, once said, “Quality means doing it right when no one is looking.” The selection of the appropriate grade Fuel Pump for a vehicle ensures higher performance and long-term savings due to reduced chances of breakdowns or early replacement.
