Re: How low can you run your fuel tank

I found out the hard way that one should never trust the fuel gauge. Ours was reading 1/4 tank and I was going to fill up the next day.... when we ran out of fuel.

If you're going to empty the fuel tank and you have a diesel furnace, remember to shut off the diesel to the furnace so that you don't drain it and therefore have to bleed it. Luckily I can fit inside my starboard cockpit locker, because that's how I had to access the furnace intake to bleed it.

Re: How low can you run your fuel tank

I had a single 150L single tank and yes with about 25 liters inside and big waves (20/25ft waves) the engine had problem sucking air. I guess it is not as much the state of the sea but the size and steepness of the waves. Going up an down those big waves tilted the boat a lot and the inside tank wall was not sufficient to prevent all fuel to go to one side.

Regards

Paulo

Forget the engine, I'd have a problem sucking air in 20+ ft waves

I agree. Seems to me running your engine in 20+ foot waves is poor idea. I would instead lay on the cabin sole in the fetal position and cry.

Sorry guys, I did not want to give the impression that I sail in storms.

Actually along the Portuguese coast you can find sometimes some really big waves that form in big Atlantic offshore storms but if the wind does not blow over 30K they are just impressive and not dangerous because they don't brake and are not short period waves.

I was talking about one day that I got some of those in passage. Nice sailing, downwind with 20K wind except that near sunset the wind died but not the waves and what has been a very pleasant sailing day turned from some hours in a rather bouncing experience, with an engine that worked in a very irregular way. We where near port but take a long way to reach there, doing about 2/3K speed

Well, near shore they break:

Re: How low can you run your fuel tank

I cut the sole with a hole saw and inserted a bronze deck fill to make it easier to read my fuel gauge. Now I don't have to lift floor boards in order to verify fuel levels.

Re: How low can you run your fuel tank

That looks really nice, BluesHarp. It would be easy to ready while lying in the fetal position on the floor in 20+ wave too. I thought about doing the same thing with a glass lens, but in the end decided that it was not that much of a chore to lift the lid when I needed to check the fuel level, which really, for me, isn't that often.
