KW 230 BR- not taking gas in tank

2014 230 BR will not allow any gas to be added to tank.

It just comes back at you. Tried pumping very slow, but still no good.

Has been fine- ie last week- topped off.
Yesterday, 1/2 tank (according to gauge) and didn’t get a gallon in.

Fill is on port and vent on starboard. No changes to boat.

Both times has been on trailer, both times about 1/2 tank.

Motor runs great- yesterday @ 5200 RPM. No problems. Idle is good also.

Suggestions??

Had a bass boat one time with same problem. Finally found the hose going from tank to vent port was kinked

Pulled vent-
Clean.
I took compressed air and forced into vent. Could hear gurgling and about 2-4 ozs of gas/water came out.

Wonder if that blocked the vent?

that happens with these new gas systems-
i just cut a water bottle in half and blow hard into the tank, in turn it builds up pressure the blows the fuel out of the little tube. be quick or it blows out on you.

Even if the vent is clear, if there’s a “belly” in the hose it can hold gas and prevent vapors from flowing.

Vent line should be as short as possible and no kinks/bellies in the line.

See if it has a carbon canister, Mine is in the front anchor compartment (250BR Key West). The vent line snakes around the whole boat. If you top these new boats off with fuel and over fill it the fuel goes into that canister and ruins it and causes the issue you are describing. If it were mine I would bypass the canister ones the problem started.

Too many things to play with!!!
Factories and Gov should subscribe to the KISS principle…

Thanks for the input…!!

I assume you have to pull existing canister to know what to buy?

Any way to know if canister is faulty?

Any idea which comes in 2014 230?

DRMajor

I would confirm if it had a canister and if so get the model number if you wanted to replace. If it were mine I would find some stainless hose clamps, 2 barbed couplings and a short pice of hose to eliminate the problem for good.

Yes… got rid of it on motorcycle.

Here is the schematic showing you the canister and all, on the 4th page

Thank you… Wow, how complex can they make it?

Of course, one cannot get to most of this.

Gotta be a contortionist to get to that.

Any wat to know the canister is faulty?
