This past weekend went to put gas in my boat but as I start putting in gas it was overflowing or gas coming back up . Could there be air in the gas tank or someting ? How can I fix or check this ? As never had this issue before. It’s 2015 sailfish 270 cc boat with twin merc 150 Anybody had same issue or what to do ? Let me know , thanks

Maybe check the vent, it's possible that insects made a nest and has it clogged. I also think there's an inspection cover where you can view the fill pipe from inside you could take a look in there too make sure nothing collapsed.

Oh ok will take a look Also do you know if my boat comes with some epa vent valve system or canister ? As some body was telling me about some new epa regulation was passed after 2012 and boat had to have it so not sure about that or if my boat has it or anything ?
And what about if I try blowing air in the vent tube or small hole that is by the gas cap would that help u think ?

I had a boat that was finicky about taking on fuel sometimes. I figured out that the vent line had a short drop in it and if that low spot got filled with fuel after rough weather cruising it wouldn't breathe well to let air out as the new gas came in. Solution was to blow that vent line clear and to avoid overfilling the tank especially if cruising in waves.

Oh ok will try blow the vent line , but my boat had low fuel in it and did not put in much. Another thing have any of you guys smell fuel in the helm area or in the cabin only after putting in fuel? And have check in the bilge area and the tank area to make sure I do not see any fuel and I don’t see any at all or smell it there . And after putting in fuel the smell goes away after a few minutes and I never smell the gas again until I have to put in fuel and the smell only last for a few minutes and goes away. I only smell the fuel after putting in gas. Which is strange becuz I don’t see any fuel any where and the smell goes away after a few minutes . I don’t believe there is any leaks in the tank as my boat is a 2015 and plus I don’t see any fuel in the tank area or smell it there after filling Any thoughts on this or any you guys had that same experience?

You might see if this helps as it fairly well covers current design fuel vents and diagnosing a problem. If fuel or water ever got into your canister the canister should be replaced. However, if the line from the tank to the canister or the vent line from the canister is blocked you'd have the same problem. Just need to do a little diagnosis to determine where the problem lies. Good Luck!

Ok thank you will check that link out But does anybody know where the canister is in my model and year boat ? It’s a 2015 sailfish 270 I guess the 2660 would be the same If anybody could tell me where to look for it would be great

My boat doesn't have any of the epa crap. Not sure what year they started putting that on boats? Like Finatic said also check the vent.

Ok just got back from my boat and I think I fix the issue not sure yet until I fill up with gas again But the vent hose was not connected at all by the gas cap was just hanging there and it did not just come off bcuz no clamps was on it and also a I could not push it back on as the filler hose clamps screw was in the way , and was hard to get it move had to use a hammer and Long screw driver to push it to the side . Also the green ground wire corroded away and broke off half way under the floor so was not connected either. So had to try hard to fish a new wire thru which was hard. But anyway got both ground wire and vent hose connected now. Not sure why that vent was not connected as I bought the boat 5 years ago and nobody touch that so don’t know . Do you think that was my issue with the vent not working and should fill good now ? And also what was that green ground wire for and do ? Oh and also I just blew wire thru the vent hose just to be sure to clear anyting . See pics

Well that explains why you smelled gas after filling. Glad you got it reconnected, along with the green ground wire which is there to ensure no static spark between the tank and fill occurs with a filling hose nozzle. One of those safety things to keep explosions away, so kind of important. The spec requires less than 100 ohms between fill connection and tank, with new wire and no corrosion you should be good as that dissipates static build up so it can't spark. Well done Captain!

Thank you sir. But still have to find out if that was really the cause or is issue with it not venting good and gas coming back up. Won’t know until I go fill up again So you really think that was the issue with that vent tube not connected and should work now ? Thank you

Well you fixed two obvious issues, the vent connection and the ground wire. Were you able to verify blowing through the vent worked? If so, it should let air out when filling up.
BTW you can go back and add photos by editing your prior post.

Well did not get to see if connecting that hose or blowing work. As did not get to fill up with gas as yet.
