I recently purchased a weber downdraft, a 6v carter fuel pump and a fuel pressure regulator. I guess my first question is (and i should have asked before buying it), do i really need a fuel pump for the weber carburetor or will gravity flow enough fuel? Since i think i will probably need the fuel pump based on what i have read on other threads. Im wondering if anyone has suggestions on wiring the fuel pump. I will be adding a inline fuse (still need to find out how many amps this pump should be drawing). I plan on running the power through a relay controlled by either a toggle switch or the ignition switch. I like the simplicity of the pump being tied in with the ignition switch but i read on another thread that the gentleman was turning off his fuel pump before turning off the motor so the carburetor wouldnt flood the motor. Pretty sure a properly adjusted carburetor shouldn’t be flooding the motor while sitting, but that is why im asking for suggestions. Any thoughts?
