40 johnson elcec. Vro removed by previous owner,oil only. Fuel pump side went bad on me. Removed all the rest of vro componets, added New Vacuum fuel pump and it wouldn't keep up when on plane. Replaced bulb with new johnson bulb. Can't find any fuel or air leaks. I am running an electric pump off the acc wire (key controled) with a manual kill switch. Don't like it but it is all that will work. Is there a pulse limiter that goes in the side of the block that i am missing or something else?
