    Sanity check - fuel rail flow direction

    Just a quick sanity check before I finish off my new fuel lines - I'm doing my own head in!
    The fuel flows straight into the fuel rail, then back out through the pressure regulator and then returns to the tank right?

              Yeah, must flow through the rail to the regulator, else it wouldnt regulate the pressure. I made that mistake when i connected my aby fuel lines the first time
