Cannot refuel at dock on 2015 sweetwater premium

ekay

I have seen this issue with gas back splashing while trying to put fuel in at  dock. But don’t seem to have a solution. Read many explanations why this is happening but no answers to how to refuel without back splash. I have tried a siphon, but as soon as flow starts really good, gas flows out of fill. I have contacted my dealer, service people  and other owners. No solution is evidently available. Except, to fill the tank with a funnel 2 cups at a time. This does not seem like an acceptable solution. I am frustrated.

I suggest replacing the anti siphon valve on the fuel tank first and if that does not work you'll want to check the vent line. This pressurization happens when the tank cannot vent the vapors.

I have the same problem and can’t believe there isn’t a solution. Ekay and I can’t be the only 2 people with this problem. This past Sunday it took me 32 minutes to put in 20 gallons of fuel. Not acceptable.

I have a 2003 Sweetwater

how do I replace the anti-siphon valve or check the vent line?

I just purchased a 2023 Monaco and same issue took an hour to put in 8 gallons a little at a time as gas kept splashing back out?  What is the fix?

I have a 2020 Sweetwater.  I had this problem.  I would unscrew the vent line at the tank to fill up no problem.  I could not for months figure out why the back flow was happening, coulding find anything wrong with the lines.  Then my fuel cap door would not stay closed.  When I removed it to inspect and clean, I discovered mud divers built a nest in the hole that is the vent.  Clean that out and I no longer have to disconnect the vent line at the fuel tank to fill up.  Hope this helps.
