The automotive fuel system is important because the fuel pump bypass valve also operates in compliance with the flow and pressure of the fuel. This part normally runs at 30 to 60 psi, which varies by vehicle model. The bypass valve then opens at a preset point allowing surplus fuel to return to the tank. This serves as a safety feature to prevent damage to the fuel pump as well as so the ULX-pump continues functioning properly.
Improving the efficiency of fuel delivery Even the most efficient bypass valve can make an underperforming fuel delivery unit up to 40% more reliable. Bypass valve is "critical to protecting the fuel system, and ensuring that the pump remains in its intended design window," says a noted automotive engineer
Fuel pump bypass valves help keep constant fuel pressure under all engine demands. For example, when accelerating hard the fuel pressure could be changing substantially. By keeping the system fully closed until high-boost, the bypass valve helps dampen those fluctuations; a smoother-run engine is small boost practical up. According to studies done by the industry, high fuel pressure can improve engine efficiency up to 15% leading to better fuel economy.
A bypass valve failure may let in too much or too little fuel, resulting in power loss. According to news accounts, some 25% of fuel system problems are due to faulty bypass valves. These fatalities can be quite low with regular inspections and maintenance.
Many modern bypass valve designs also incorporate additional components and features that increase the precision and longevity of their function. Other models employ electronic control which allows the device to continually adjust its units of fuel based on ever changing engine conditions. One of the top automotive company says,"Invest in high quality fuel system components and get a good run product life and best performance out of it."
Get some details about fuel system parts following the Fuel Pump, it is important to understand how a Bypass Valve applies and why in all mean its keeps your fuel delivery good. This knowledge will allow vehicle owners to take steps towards the health of their fuel system and ensure they get maximum performance.
