2012? Send it back!

Even dragging it back from Luxembourg will be easier than fixing a leaking tank, unless it's a leaky fuel line or gauge.

Hey Gilles,

Check the fittings and connections of the filler pipe and the breather pipe - you might be loosing fuel while filling. Also check the connections to the fuel supply to the engine and the plate where the fuel gauge sender enters the fuel tank.

I'm guessing you've just filled the tank and noticed this? Get someone to fill a little fuel while you watch.

but i had this issue from several months and when i ve been to the isle of Wight, after consume 149L from my optimax gauge i filled in with 150L back. that means to leakage. now i just put 40L and get more than 1L in the blidge pump aera. and engine is still consuming petrol, water separator is still full ...is this fuel line check really needed ? what u think ?

Fuel in the bilge just means a leak. It could be from:

1. A broken weld in the tank. Very bad = deck removed, tank removed.
2. A loose fitting, a broken hose, a bad gasket. Maybe easy to find and fix.

I had a leaking fuel filler hose once that did EXACTLY what you are seeing - about a liter of gas in the bilge after filling. I finally say it leaking into the console after a fill and a new hose fixed the problem. However, it could be ANYWHERE on the fuel system, but unlikely to be in the engine fuel line if the engine is running OK.
