Electronic Fuel Injection Fuel Pressure Regulator Flow Rate
Written by wolfems on September 10, 2009 – 9:28 am
If you imagine a huge fuel pump. It pumps a huge volume of fuel. That fuel travels along a fuel line, some of it is used by the fuel injectors, and then it comes to the fuel pressure regulator. The only problem is that the fittings and internal galleries on this fuel pressure regulator are much smaller than the fuel line and fuel rail, and so the regulator cannot regulate the fuel pressure down to where it needs to be.
