Working on my Dad's new to him 84 Dodge Rampage. I'm replacing the brake lines and some fuel lines. I'm trying to figure out the fuel routing. There is a line going from fuel tank down the left side and to the mechanical fuel pump. I'm assuming that is the fuel supply to the pump. There is then a line from fuel pump to fuel filter, I'm assuming that is the fuel supply to the filter. There is then a line that goes from the side of the fuel filter, back to the tank. What is this for? Then there is a line coming off the top of the fuel filter, to the carb.
Don't know what the line on the side of the filter is for?
