Increasing the efficiency of a Fuel Pump involves several ways that ensure its ability to function performs at its best while prolonging its life. Efficiency could be improved effectively by keeping the fuel filter clean. A clogged filter restricts fuel flow, forcing the hard work of the Fuel Pump; hence, reducing its overall efficiency. However, the less cumbersome process would be to replace the fuel filter every 30,000 to 50,000 miles to ensure that the fuel system performance is maintained. A clean filter can increase Fuel Pump efficiency by up to 20%, as it reduces strain on the pump and ensures a smoother fuel delivery.
Another very effective way to improve the efficiency of a fuel pump involves maintaining correct fuel levels. Running the vehicle on less than a quarter tank of fuel can eventually cause the pump to overheat because the fuel in the tank cools the pump during operation. Over time, this may reduce the efficiency of the pump by as much as 25%, thus severely shortening its operating life. Keeping the fuel tank at least half full not only helps cool the pump, it minimizes the possibility of sediment in the bottom of the tank being drawn into the fuel system and causing further damage to the pump.
For high-performance driver seeking high efficiency, the answer is to upgrade to a high-flow Fuel Pump. In a high-performance engine, particularly those with modifications such as turbochargers or superchargers, much more fuel is needed than what stock Fuel Pumps can deliver. Normally, upgrading to a pump that delivers more LPH, around 250-400 LPH, should give the needed fuel to the engine without overworking the pump. That not only improves efficiency but also keeps it from running lean, which might cause damage.
Electrical factors can be one of the most influential things when it comes to your Fuel Pump’s efficiency. Ensuring wiring conditions and the fuel pump relay are in good condition is extremely critical to avoid any electrical malfunctioning that may lead to inconsistent power delivery. A well-functioning fuel pump relay, which controls the electrical supply to the pump, supports consistent fuel pressure. If the relay goes bad, it may not deliver the proper pressure needed, which in turn reduces performance and efficiency. Replacing a faulty relay can be replaced for anything from $20 to $50 but is small compared to the $400 to $800 it could take to replace a worn-out fuel pump.
As Carroll Shelby, an automotive expert once said, “Performance is the only thing that matters.” Keeping the fuel system clean, replacing pertinent parts when needed, and providing electrical stability will go a long way in boosting the efficiency of the Fuel Pump for optimal performance of the vehicle.
