I haven’t seen the tank and line mentioned yet….Air leaks at the fuel fittings can leak air in but not fuel out, sometimes. Sometimes, the primer bulb gets hard; but that’s because you can find the check valve in the ball has not only fallen apart inside but worked itself back in, backwards! I have seen some of the newer, plastic tanks with the plastic pick up tube leaking air where it attaches at the top. I just repaired an oldie-but-goodie OMC, single hose, metal tank, where the whole brass pick up tube was cracked, up and down the length of the tube. (Maybe that’s why I found this one at the dump.) Anyway, the Cardinal rule of separating engine from boat, when trouble shooting, still may apply here. Just sayin’. I would try another tank and line before going too nuts on the motor….
Long live American manufacturing!
