Fuel tank breather

[Hightower]

Don't think I'd like a tank breather at the front of a consol like in the picture.

One stuffed wave and you'd have water in the fuel.....Wouldn't you?

Similar breather on Kantndra. Very bad stuffing recently and no problems.
It would take a lot of pressure to push the water into the tank. And by the time it gets mixed with the petrol your filter should sort out any small drops.

That much said I am currently in the process of flushing out the tanks just to be safe.

I wouldn't have put it there either, would have put it on the back of the console, but I guess it was put there when the boat was built.

I think it would take a hell of a lot of water arriving at high speed to force any amount up into the narrow slot at the bottom and then up through the gauze thing inside, it does look to be a reasonable design as the water would have to hit it travelling upwards to stand any real chance of getting in, unless you submerged the whole boat. Could be a risk though - but I don't intend to get that wet if I can avoid it better than fuel leaking all over the battery anyway, which was what was happening before!

That's not safe. Welding arc is >5000 degrees C-water turns to steam at the weld site and high temp steam is almost as good an oxidising agent as air.

Best way is flush with warm water+detergent, allow to dry then fill the tank with inert gas at low pressure.
