Thanks guys,
I turned on the electric fuel pump with the site plugs out and the float did rise so that it was visible, and the fuel level appeared to be at the bottom of the hole on the primary side and dribbling out of the hole on the secondary side. I suppose this is normal. It concerned me that one side remained full while the other appeared empty.
Is it critical that the level should be set while the engine is running?
