OKay, I don't think I will ever relocate my vents.
So with that said, do I just stick a hose up there and blow air into the vents? If there is some blockage, would it then go into the gas tank and create even more headache? I'm purchasing a new water/gas separator filter to see if this is the issue. I'm new to a lot of this, so it helps when you guys "break it down" for newbies like me... Thanks |

Blow air into the hose coming out of the tank, before the bulb. That would clear any obstruction in the fuel line and pick-up tube. Do it slowly, and have a friend stand near the gas cap and listen for a hissing type sound. That would be your fuel tank vent. It lets the pressure inside and out side of the tank equalize. If you dont hear a hissing sound shortly after blowing ait into the tank you probably want to loosen the gas cap. If you dont have a vent that could be the problem instead of a blockage. With out a vent there is no way for air to get into the tank to take place of the gas going out of the tank. It creates a vacum in the tank, The fuel pump only creates a few ( 2 to 5 ) inches of mercury, or vacum - to draw the gas out of the tank. once the tank vacum equals the vacum of the pump it becomes tie and gas isn't going anywhere. If you tank is in the deck ( you'll see the access hatch in the deck) it should have a deck plate that allows you to get to the fittings on the tank that attach to the fuel fill hose and the vent hose. Most of the time it's the deckplate closest to the front.
The smaller hose is you vent hose. You can take it off at the tank and blow thru that and if you should be able to track it down then. If it does not have one, you may want to install one. |

Hey, Skool...that thru-hull was there when I got the boat...ANOTHER one on the other side...pulled 'em out and resealed 'em and plugged 'em off...never been used far as I know...think previous owner was thinkin raw-water wash-down or somethin'...it's been so d--n HOT lately, been thinkin' about running hose from there straight to helm for a 40 mph FACE-SQUIRTER :o...
Mudda...keep in mind gas FUMES are more volatile than gas itself...we'd hate to hear you blew your a$$ up down there in paradise :o...

I found the problem (although another has been created).
It wasn't the filter or the line or the vent. It was the little clip thing that you click onto the engine at the end of the gas line. I just bought some new ones and they fit, although I did realise that they didn't "click" into place like the older ones (I have new one attached to internal tank line and old one attached to container line). So what would eventually happen is it would work it's way off the gas end on the engine and stop flowing gas into the engine, thus the periodic shut downs. So I was happy to discover that.... but... |

Pull the plugs and squirt the cylinders down with a lubricant, try turning the motor over by hand before reinstalling the plugs
