Shortly after i had a new fuel tank installed i discovered a problem a boat gas tank vent problem.
Problems filling boat gas tank.
Since it s not pressurized filling it can be more troublesome.
Owners should only open the fuel cap for refueling.
The nozzle continually shut down as if the tank were full until a gusher of gas spewed from the vent.
A boat fuel tank overflow can be caused by a clog in the vent.
It s already been determined that the issue with a lot of boats is the vent tube not providing adequate vent while filling causing the gas to back up.
Is the fuel tank vent clogged.
The fuel tank vent is located on the outside of the boat normally relatively close to the fill port on the gunwale of the boat.
Original equipment manufacturers mechanics and boat dealers as well as the american petroleum institute the steel tank institute and other well intentioned professionals have offered widely differing opinions in the past on whether to leave tanks full or empty during storage but recently they have come to the same conclusion.
Taking a look on the outside of the hull and seeing if the vent is even there if it is corroded broken or upside down.
If fuel gets into the water you can get into trouble quickly so you can t continue to boat with a small leak.
The video didn t say a single thing about why we have a hard time filling our gas tanks it was an advertisement for a new tank fill system perko has come up with.
Knowing the tank can t possibly be full i keep working on filling the tank at a rate of less than a gallon per click until 10 12 possibly more gallons later i see gas come out of the tube.
A boat s gas tank is different from your car s gas tank.
It was difficult to put gas in the tank.
The first time fuel is introduced to the a fuel tank be aware of the interaction of cold raw fuel vapors replacing air on occasion a vapor pressure can occur producing spit back anomalies.
Then i could fill up just fine.
