Strong gas fumes after minor haulout joltng
Yesterday I hauled out my Tartan 34c on the club's Brownell Trailer
The gas was filled and stabilized a few days before. The engine started well yesterday and ran well all season with a new carb and filters. When after adjusting stands i went below to the cabin and smelled strong gas fumes. I am thinking that jolting during haulout may have stuck the carb float or less likely, the very full tank sloshed out somewhere? The fuel was left on during haulout and only shut off an hour or so later when closing up the boat. The fumes still remained this morning I have had stuck floats due to fuel last 'season, but never this season or so abruptly have yet to investgate Suggestions appreciated. |

Check the hose between the deck fill and the tank. Mine just crumbled in my hand. Easy fix - thought I had a leaky tank.

Investigate with power off and boat well ventilated. Check the bilge with your nose. Really strong gas fumes are probably not just a stuck float valve. It could be something like a loose hose fitting above the tank which only leaks when the tank is full. Jolting on the trailer is not likely to create a new leak. Do not start the engine before checking for fumes and fixing the leak. If you can smell gas fumes anywhere but at the carb air intake, it is serious.

Hi Art,
Had a friend with a Tartan 34. If I remember your engine is in the middle of the cabin beneath the floor boards?? Any sign of gas in the bilge? All good suggestions the guys have mentioned.

The engine in a Tartan 34c is indeed in the cabin, but not entirely beneath the floor boards. When the engine enclosure is closed, the blower pulls air through the bilge from a vent in the forward chain locker. But, when the enclosure is removed the blower draws mainly from the bottom of the standpipe rather than the bilge. As Art may have experienced, if there is fuel under the engine or deeper in the bilge, the blower can't clear the fumes effectively when the engine cover is off.

Thanks for the replies guys much appreciated
I have had a stuck float last season which loaded the bilge with a qt of gas before detected. Flushing the man passage fixed that then. This time filled the tank on Wed hauled Sar. Ran fine to dock where t sat 4 hrs waiting my turn to haul - fuel was left turned on -was not sure of haul out ordering. fuel accumulate could have started then. On these boats fuel can gravity feed when facet is off and potentially empty tank into bilge. Too bad facet does not include a fuel shutoff option as well as shutting itself off. When done using boat for day always shut off the manual valve near tank Th odor was there yesterday after overnight, but not as strong. Normally would have checked bilge then but live 50 miles away after helping other boats haul was xhausted. will go tomorrow and report findings Thanks best to all Art Last edited by ArtJ; 10-05-2020 at 08:17 AM. |
