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.
