Refuel Issue
 

Can't refuel the car without constant clicking off...its getting a bit annoying...

Has been doing it since I have had the car, S60 2008.

There are a total of three pipes between the refuel cap and the tank.

1, the thicker one carrying the fuel.
2, a vent that has a 180 degree pipe attached to the end, assuming this is a permanent breather.

Have gently checked these are clear with a rod.

The third has a large tube in it which I am assuming contains some kind of one way valve for venting during refuels. It goes from the tank and finishes internally to the top of the filler neck.

It's hopefully in the picture attached. Does anyone know what it actually is? This isn't my one its a photo taken from eBay.

Much as it will cause some debate I am contemplating removing whatever this is...

Thanks in advance for any help you can give.

Other than that the car is ace!!!
