The fuel pump plays a vital role in handling a load by availing sufficient fuel supply to the engine to equalize the changing conditions of load. Increased loads-meaning rapid acceleration, towing, or driving uphill-requires increased fuel. A good fuel pump should introduce sufficient fuel and maintain constant pressure within the range of 30 to 80 psi for appropriate engine response. In the case of an adequate fuel supply failure by the fuel pump, usually quantified by 90-255 LPH flow rates depending on applications, the engine may suffer from power loss, efficiency drop, and probable stalling.
When there is a heavy load on the vehicle, fuel pressure is maintained by making the fuel pump work overtime. In high-performance cases, during racing or hauling along heavy trailers, there is a need for fuel pumps capable of higher flow rates. For example, a high-performance fuel pump can handle over 300 LPH for flow rate application to ensure that the engine does not starve under heavy loads. When the pump cannot keep up, the lean air-fuel mixture may result in poor acceleration and possible damage to the engine by knocking or overheating.
Other factors affecting fuel pump performance under load conditions involve electrical aspects. Normally, fuel pumps operate in a voltage window ranging from 12 to 14 volts. If, for some reason, the electrical system is not able to supply enough voltage to the pump-because of corroded connections or weak batteries, for example-the pump will never achieve the pressure and flow it is designed for. In such cases, performance degrades, especially when the load is higher and requires constant fuel delivery.
Besides, consistent fuel system service is necessary for heavy-duty loads. Poorly serviced fuel filters may reduce the fuel flow up to 20% and impede the pump’s ability to deliver adequate fuel when its demand goes up. According to mechanics, replacing fuel filters every 30,000-50,000 miles can make a huge difference in ensuring that the pump functions effectively, especially for those who constantly carry heavy loads.
As Henry Ford, the founder of automotive, said, “Quality means doing it right when no one is looking.” The Fuel Pump must be reliable to handle and manage the load effectively so that the performance of a vehicle can be catered to.
