I need some one to explain something to me. I was looking at the diagram on Pelican and something didn’t seem right. If you follow the “Flow” arrows you don’t reduce the fuel pressure until after it goes to the injectors. Shouldn’t the fuel pressure regulator get the higher pressure fuel from the pump before the injectors? Maybe I don’t fully understand, but it just doesn’t make since to me.
I’m redoing all the fuel lines in my car (was carbs, but going back to FI) and need to know if the Pelican diagram is correct. Help please!!! Thanks, Mike Attached image(s)

That picture is right. The pressure regulator sets the pressure in the high pressure side and ALL the fuel injectors draw from that set pressure. Think of the pressure reguator as a valve that opens when the pressure is too high and closes when it drops and maintains the most even pressure it can for the injectors to draw from. After the pressure regluator, there is an open tube to the gas tank and pressure drops.
Do it backwards and each injector will be drawing gas at a different pressure, particularly the one that is farthest downstream. Ken |
