I need some help remembering how exactly the fuel lines go. The car is a 73 1.7 w stock fuel injection and pump in stock location. The pump has a S, D, and R on it and I'm pretty sure thats obviously supply, divert, and return. So my 1st question is where does the D or divert line goto? The 2nd question is that it looks like once the supply line gets to the engine it 1st goes across to the driver side to the regulator then to the fuel rails and back down to the return side of the pump is this right? Thanks in advance for any advice and/or pics.

The regulator is like putting your thumb over the end of a garden hose. The pressure in the hose goes up when you do that, right? So the pressure regulator is like an adjustable thumb that keeps the pressure in the hose (the high-pressure loop of the fuel system) at a given pressure.
So the circuit goes from the pump, to the fuel rails, to the regulator, and back to the tank. --DD |
