1977 Merc Balck Max 175 HP<br />I forgot to open my gas tank vent. Motor ran great for 10 minuted then starved for fuel and stalled. I opened tank vent to relieve much suction. Re-primed bulb. Motor never ran right after that. rough running, can't get over 2,000 rpm. Breifly it ran good for about 30 seconds. I'm thinking I sucked a gasket loose in the fuel pump. Upper check valve (carb side) gasket looks deformed. Could a fuel pump rebuild kit fix my problem?
