Re: Help Anyone...
Just because the pump does not have a vent does not mean it's not a "marine" pump. There are plenty of fuel pumps which qualify as ( Dr. Evil raising hands and saying quote) "marine" fuel pumps that don't have vents. My 1975 merc engine had a couple ounce glass bottle off the pump with a sign in it saying if fuel present replace pump. Most of the time that port off the pump is just plugged. The pump fails, as in the diaphram ruptures, it just stops pumping. Fuel doesn't go anywhere. All the pump has to do is not dump fuel into the bilge if it fails, or a better way of putting it would be to say not result in any type of situation that's hazardous since it's dealing with gasoline. And it's funny because all the, quote, "auto", fuel pumps don't vent anything. They fail, they don't pump fuel, that's it. They don't leak anything anywhere. But it seems like all, quote, "marine" fuel pumps have vents. Shouldn't we be asking why did mercruiser or OMC, or maybe USCG, use or require a pump with a vent nipple? Why "vent" fuel anywhere? And in addition why use a stupid push on plastic hose that is not secure? Seems like an accident waiting to happen, chances are the hose got knocked off and just dangling, and if the pump fails it's just going to dump fuel into the bilge. Funny how the fuel line must be USCG rated for heat and fire, and I understand it's under pressure and flows a lot more fuel, but use a p.o.s. plastic hose for a vent line to the carb.
I'm sure the, quote, "automotive" world doesn't design things to be hazardous, and just dump fuel when it fails, and when you look at the traditional mechanical fuel pump that's fit on your typical chevy, an "auto" pump sure looks safe, if not safer, than a "marine" pump with a vent.
