Fuel came out overflow

[Ifishmuskie2]

1994 StarCraft super fisherman 190. I put fuel in (on dry land) and stopped when it kicked off. I didn’t put any more in after it kicked off. It took 100L. When I slowly pulled away from the pump about two cups of fuel came out the overflow. What can I do to stop this?

don't fill the tank as much. remember, fuel is stored underground at 55-60*f. when you fill the tank, the fuel warms up and expands.

Don't fill until it stops. Fill until the gauge reads full.
Install a racor lifeguard otherwise.

If i fill until it stops I'll get slosh out the vent until the level drops on take off... the life guard, while expensive, will stop this. With how low my tank is and how low the vent is I am prone to it... filling until the gauge reads full is easy.

There upis also a device that installs in the vent hose, that makes a whistle sound when filling. When the fuel pressure from filling reaches the vent hose the whistle stops. This is where you shutoff the pump to let the fuel settle and create an air pocket so no fuel comes out. Another thing that helps is to have an upward loop in the vent hose before it exits the hull.
It normally creates enough pressure to shut off the pump before fuel comes out. Also keeps any water from entering thru the vent hose and contaminating your fuel.

This is what I have on my boat, it works great.

When you fill to the point the hose clicks off, the tank is over full, and the fill hose is filling up and fuel is about 6" below the vent and filler.

As indicated, don't fill it as full

I think I’ll try the don’t fill it so full method.
Thanks.

Huh and there was me thinkin it was a trick question

Don’t know how big your tank is, but do yourself a favor and only put as much fuel in the tank as you will need for the day or week.

The extra weight uses more fuel, decreases performance and increases the chance of the fuel going bad from sitting in the tank for an extended period of time.

 

[Ifishmuskie2]

Yes.
I’m just getting used to this boat. I’m not sure how much gas I need for a day or how big the gas tank is. Trying to figure it out while not running out of gas.
So far The tank is at least 24gal. And I figure 10gal will do for most days fishing.

 

[Chris1956]

Gee, a 19 footer could easily have a 35G fuel tank, or more.

My 19 foot sterndrive had a 35G fuel tank, which was pretty standard, and my 21 foot outboard boat has a 63G fuel tank.

If there is a hatch that exposes the fuel tank, it may have a capacity plate. Alternatively, carry a full portable tank and run the main tank dry, and refill it.

When filling, I put my ear near the nozzle when I'm near full and can usually hear the tone change when the fuel starts filling up the fill hose. Hard to do if it's noisy as you're filling

You'll get the hang of it
Either that or move the tank vent up, or replace fuel fill with combo fill and vent so they are at same level

I never fill mind all the way up. The tank is 44 gallons so it’s easy to estimate each 1/4 of a tank is about 11 gallons.
