Fuel tank leak

Mistroma said:
It seems like a time-consuming method of not confirming the source of the problem. It might leak because you didn't seal something perfectly (hose, vent, etc.).

It would have taken much less effort to simply removed the hoses many weeks ago. If the leak stopped then you only had to add some fuel to see if it started again. No leak at this point would mean it wasn't the tank.

At least you can compress the timeframe now as any leak will be much faster when the tank is pressurised. I would still have removed the hoses before starting. Bending, squeezing and so forth might damage them and they might still be leaking for all you know. Total isolation removes that problem completely and it should be simple to seal the open pipes (e.g. Short length of hose with clamp).

The tank was isolated a while ago (I found a young mechanic working on a neighbors boat and poached him)
The tank continued to leak for a little while. Because of other issues with my life, time wasn’t an issue…and this season there will be a lot of unemployed superyacht mechanics available..(I don’t wish to make light of a serious situation).
 
Right now I’m having a great night out!!!
Pastrami bagel, onion rings, falafels, guacamole Budweiser and pression, hot dog for the chien.
Aix-en-Provence is a great town, terrific night life. The Paris of the south

You missed posting that vital step or I managed to miss your post. It does point to the tank if you are saying that the leak continued for a while after disconnecting and then stopped at a later date. A small leak could have been the hoses and engine leaking but that would have dried up pretty quickly and only been a small volume.

I can't understand why you'd re-connect the hoses again, that wouldn't make any sense. I assume that you left them disconnected and pictures show small hose ends screwed on and then clamped to seal. That would make sense.

Yes…my fault, I did miss reporting that?
The hoses are just on to allow me to clamp them..they are not the fuel hoses and they don’t go anywhere

I can’t remember ? three I think and I kept on for ten minutes and then repeated. I don’t trust my pressure gauge but when released a lot of pressurised air left the tank

You might be better off making a manometer and watching for a drop in pressure that way, far more sensitive than a poxy little pressure gauge.
 
Thanks Spider….it wasn’t the relentless personal attacks that made me leave Discord….it was a small group who complained that I was ruining the experience for them. I was a Johnny come lately and it was never my intention to spoil the forum for them…so I left quietly

Well from the info thus far bearing in mind the new position / tilt on the hard they usually are blocked bow high .Well higher than when afloat .
No point ripping the tank out if it survives a pressure test .
After a fix 439 # posts in seemed to have covered everything except core soak .

re Discord …….Yeh needs clarity? Now it’s been mentioned in this thread .
