    As per another post on here recently, if you have a rubber priming bulb on your filter housing, you can get a split in the rubber which, although it doesn't produce a "classic" leak, draws air into the system, causing spluttering and loss of power.

    hi jockaneezer thanks for explaining that to me, is it like a diaphragm inside the filter housing? That can split like on a carburettor thanks for your help.

    I don't know whether all versions have them. If yours has there will be fuel hoses connected to the OS end of the cylinder head one of which goes to the filter. If hoses leak on the suction side there is usually no indication: the fuel pump draws air in & when the engine stops fuel falls back to the tank - again drawing air in. They can be a bu**er to spot.
