1990 Four Winns 205 Sundowner won't accept fuel

[boatkrazi]

Hey Gang - I'm wondering if anyone else has this same problem.
I recently aquired a 1990 Four Winns 205 Sundowner Cuddy. I love the boat, but it has a mystery issue:
On the trailer, the boat accepts a modest amount of fuel, but certainly not a full tank's worth, and at the fuel dock, the tank won't accept fuel at all. In fact, I can actually see fuel floating at the top of the filler neck near the gas cap.
You might think: "vent hose is plugged" so I unhooked the vent hose at the tank and blew through it, and it flowed fine.
I can't imagine the main fuel fill hose would suddenly develop a kink, but who knows?
My next test is to un-hook the vent hose at the gas station at a point where the tank won't accept any more fuel and see if this remedy's the problem, if so, then the cause is still the vent hose.
But, assuming the vent hose is not the issue, and the main fuel feed from the filler cap isn't kinked, is there some component inside the tank that would cause this?
thanks!

It's already full? (don't discount this theory. Another guy had an issue, and his tank was COMPLETELY full, that's all.)

^^^Agree! There's only three possibilities - blocked filler hose; blocked vent hose; faulty fuel gauge ( tank is full ). You've eliminated one - the fact that the tank accepted some fuel indicates the filler hose is ok, so
that just leaves full tank

I wish it was already full (especially at these prices!) but anyways, I ran the boat over a distance of about 50 nautical miles, and watched the gauge drop accordingly, so I know it wasn't a full tank issue.
I'm still suspicious of the vent hose, and preparing to try the gas station test pretty soon. Stay tuned.

There are occasions were the float on the end of the fuel gage sender will become saturated and will not be totally boyante.
It may show there is half a tank when it is full.
If you cannot find any other reason, check the float.

I had a problem with my Galaxy where it wouldn't accept more than a gallon or so, even after running for an hour or more. In my case it ended up being a kinked or collapsed filler hose. The guy I had looking into it for me seemed reluctant to accept that as the cause but replacement completely cured it.
