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.

Dai,

I'm just surprised that if it's inevitable it's a poor design. fitting the breather higher would cure it I think?

My question was intended to more along the lines of why they persevere with this arrangement? do they possibly have a safety reason I've not thought of?.

Cheers- I'll try and source an anti-surge device.

Should I really be putting loops in the pipe on a brand new boat when they all appear to be leaving the factory that way? I'm more interested in why a builder apparently Thourgh in all aspect, installs this way?

We've all experienced slow fillers on cars etc, so pulling the noz out a little was the first thing I did, quickly followed by slowing the rate down-then just as quickly by - help me! help me! .

If you have a fuel management computer fitted, this should inform you how much fuel you've used, since last filling the tank (assuming you reset it at that time), which will be the amount required to fill it this time. When you're a few litres short of this, slow down the filling.

Not a solution to the inherent problem, but a way of keeping the deck dry.

I think RIbcraft use the PERKO deck fillers because they are neat and avoid the need to run a separate vent fitting. You could always change this yourself if you have a spare half hour and six or seven quid one winter evening.

Is your filler hose a larger diameter than your vent hose diameter? Also is there an anti-syphon unit on the vent hose.

I have found that the anti syphon on the vent hose restricts the air flow a little bit as well as the filler hose is usually a larger diameter than the vent hose diameter. This causes back pressure and fuel will come out of the filler hose.

Does your problem get worse on days that are hotter?

Ours dose it as well, i hear you can get a donut shaped thing that fits over the nosell of the fuel filler gun to stop it shooting back.

Iíve installed one of these and it has solved 90% of my problem. I donít get any over flow while fueling just gas surging out during trailering. But since Iíve installed this I only get maybe Ĺ liter.

I am. I think rib builders are perfect. Am I leading a sheltered or deluded life?
