Ensuring your vehicle runs smoothly is essential to its overall performance, and fuel pump pressure specifications are central to the functionality of a car’s fuel system. The majority of fuel pumps are specced to flow from 30-80 psi, depending on the requirements of the engine. For instance, most contemporary fuel-injected engines ask for a 60 psi gas pressure to maintain constant gasoline movement important for combustion. If these pressure specifications are not met, the engine will successively experience misfires with poor acceleration and fuel efficiency.
Fuel pump pressure must meet the requirements stipulated by the vehicle. An engine that produces a lot of power (think sports car) might require fuel pressures around the 75 psi mark to prevent starving it for gas. Conversely, smaller, more efficient cars may only need be inflated to 35 psi or so in order to maintain the same balance of performance versus fuel economy.
Improper fuel pump pressure regulation can have a serious effect on the entire fuel system. General Motors recalls 524,495 vehicles in April over fuel pump failure caused by poor pressure standards that leads to high-speed engine stall · Example of recalled vehicle due to reasons other than faulty ignition switches The very seriousness of this incident shows just how life-critical the role of failed fuel pumps played sparing no danger.
Fuel pump specification9 s Flow rate (often measured in liters per hour, LPH) Most standard fuel pumps flow around 100LPH to 150 LPH which is enough for most regular engines that you will see come your way, but a high performance fuel pump may take over the range of more than 250 lph necessary by larger motors. It is important to select the fuel pump for handling pressures and looking after flow rates or you will end up with an engine that does not run as well also it could cost hundreds in repair bills.
Automotive pioneer Henry Ford once famously said, “Quality means doing it right when no one is looking”; that ideal extends to having the proper fuel pressure. Correct fuel pump pressure specifications keep the vehicle running effectively and also safely.
