fueling issues

Just to see if anyone has the problem and solved it.

The boat I have, has just come out manufacturers, during the build process,any idea's I had and mentioned,they had either already encountered/solved /rectified/modified,everything had a reason normally based on function. Nothing I came up with as a good idea (for anything important) was new.

The point I'm making is the vast majority of potential problems/improvements etc, had already been thought of by the builder.

So I'm finding it a little strange when I fill the tanks up at a station the breather pumps approx 1/2 ltr of fuel onto both the tube and the deck no matter how fast/slowly the fuel is going in..

I thought that if the breather exit was threaded then you could screw a flexy pipe on and aim the the surging fuel either in with the main flow (not sure if this is possible based on it's design function) or over the side of the boat or into another container.

anybody had similar ideas?....another one up your street JW.

Your problem is probably on account of the combined Filler/breather units used by Ribcraft. On these, the breather is only marginally higher than the filler level, so some surge is inevitable. Where the 2 units are separate, it is common practice to fit the breather higher than the filler, to prevent this occurring.
I have seen anti-surge devices which you fit in the breather hose, but don't know who sells them - try local chandlers?
Also, do you have a loop in your breather hose? This can help.
Finally, when filling the tank, if you keep the fuel hose pistol seal away from the deck filler on the console, this will allow the air in the tank to naturally breathe back out through the filler hose, rather than through the smaller breather hose, which should help prevent the surge.

I'm astounded that a builder designs in this sort of nonsense. You'll need to give me more info on the filling/venting arrangement but it's always late to start solving these problems once everything is built and in place.

I'm unclear as to whether this is the breather vent or a vent to expel air while the tank is being filled.

No. What I do when it gets near to full is stop filling.

The setup is standard ribcraft with the breather/vent directly above the filler, irespective of the speed the fuel tank is being filled, the first thing you know about the the level is the surge up the breather.I set a fuel meter after filling so want a full tank every time.

I think I should not have to compromise instruments to avoid becoming a fire risk.The pump cutoff never gets a chance to operate.

Now this one could solve the problem?..... how do you know it's nearly full.

IBWET,

I listen for a change in the sound of the tank filling. You start to hear it getting louder as it gets full. Not very scientific but as you say its a fairly large backlash you get if you get it wrong.
