The correct fuel pump is...m6905. I just installed 2 last summer. To ad to the lower commentary, Paul is without question giving good advice. I would never consider a auto fuel pump on a marine app. I too have had a bad day when the pump went bad and opened the hatch and almost had a heart attack! A marine fuel pump (carter application) has the hole to hook up a hose to the carb. The hose and barb are sold in a kit for about 5 bucks (at least in my case). In any event no mater what kind of cost you incur, the correct marine carb made by carter for the 427 is the "m6905". Yes, they are expensive! But the risks of auto pumps are huge. To go a step further. if your going to risk the fuel pump, would you replace the the worn out alternator with an auto alt thats not ignition protected for 1/2 the price? if so....youre asking to blow up, expecially if the pump dumps in the bilge!
