Dan, John Cooper is correct. I had the identical problem after changing fuel pumps(traded a friend for it because mine had an 0-200 pump on it when I got it and the position of the hoses was reversed from what it should be. My problem turned out to be a bad diaphragm in the fuel pump and the fuel was reverse flowing from the header tanks back into the wing tanks. docruss --- Ercoupe Technical Discussion <[email protected]> wrote: > ----[Please read http://ercoupers.com/disclaimer.htm > before following any advice in this forum.]---- > > > Message list: > > 1.
