OK, did a little more testing. Still cant recreate the leak.

I tried to both blow air and suck air through the fuel cap - which is quite easely possible.





Also disconnected the vent hose from engine and tried to blow air and suck air through it. Also with a compressor
That was not possible - not shure if it should be.



So now I really need to find out for shure, where the leak is coming from. So I have placed dry Toiletpapir on the tank and will take a look next time I smell gasoline, and also note other things like how full is the tank. How warm. How long ride and so on.



Hello, It looks like you've added three photos to this post. They are not opening for me.
Also, there is a rubber seal under the fastener for the fuel-level sending unit.
A leak could be there if the spin-on fastener is loose, or rubber gasket under it is failing.

The vacuum line from the top of the fuel pump is attached to the emissions canister. The canister stores fuel vapors from the tank when engine is not running. Engine on - the vapors are carried to the bottom of the throttle body and then burned in the engine. There is a one-way valve in that octopus of vent lines! No fuel should be reaching up into that top line....unless you and passenger are in a moto-X !

The fuel tank cap has a hole for venting are in to prevent fuel starvation and lean running.

Most of us do not fill above that 'bar' seen down the filler neck in the tank.

And, I'm feeling a little peculiar.

Maybe differnt years or one of us has an unoriginal.

Here the model looks like mine.

And I can blow air in and out of the little hole, so should not be create a problem unless tank is over filled.

Nice Stig! I'm just starting my look for a fuel pump, thanks for posting this. Looks easy enough to do and the high flow will be nice.

Thanks!
