Slow to take on Fuel

[stg099]

We have a 2013 370 Sundancer, and the boat takes FOREVER to fuel. I can't go past the lowest setting on the gas pump without causing fuel to "burp" in the line and shut the pump off. With 2 tanks to fill the process is relatively awful.

I checked the vent line screens which were clear. Next I pulled off the vent lines and blew air through them, and all seems fine, but then when tracing the lines to look for kinks/issues I noticed that there appear to be aluminum canisters in each of the vent lines that I'm assuming are EPA/Smog requirements? This issue happens on both tanks equally, so I'm assuming that this canister arrangement is the likely culprit

My previous boats were a straight shot from tank to vent and never had this issue. Anyone else experienced this and have a solution they can share with me? I know the obvious answer is to take the canisters out of play and see if it improves but hoping to get some first hand knowledge.

Thanks all

Check and see if you have a solenoid on the fill line? My brother-in-law had a problem with filling his boat turns out there's some kind of check valve or solenoid on the fill line just like cars and they can go bad.

Has this always been a problem since new? Assuming 'no' for now...

Yup, that's the EPA-mandated carbon canister designed to collect fuel vapors. However, if you have "topped off" or if the boat was rocking quite a bit when filling up, the canister can get saturated with fuel. Possibly it just naturally happens over time, too.

I'm not sure what the relationship is between however you blew through the vent backwards (by mouth... compressed air) and how much pressure incoming fuel creates. However... take the vent line off the tank and put some fuel in - if it goes in normally, then the vent system is at fault. Get rid of the canister. If it's still a problem, then I would imagine that something is stuck in the fill hose... maybe something dropped in there? Although it's unlikely for something to have dropped into BOTH fill lines.

Woody, do you go same gas dock? May not be boat. I get same thing at some gas docks, hell even my car dont like some gas stations.
Wife had a Sonata, a particular chain gas station the pump kept triping handle. None others. My usual boat gas dock, if i hold the gas pump handle below the fill it trips a lot, but if i hold the handle upside down it fills fine.

It didn't happen to me, it was a transient boater that pulled in. I did witness the whole thing, it was definitely the water collected in the canister that caused the problem. They were drained, reinstalled, and the boat was able to take fuel normally after.

Thanks for the ideas! I will definitely be checking the canisters for water/fuel and will report back. Considering that the issue is identical on both tanks I'm hopeful that the solution could be this simple.
