it could be the pipe line from ur tank 2 ur boiler, try 2 unscrew ur connection from ur filter and blow back up in2 ur pipe. get someone 2 stand beside your tank and if they hear the oil bubbling then the problem isnt ur connection! there's a screw on the right hand side of ur filter, make sure this is screwed tight. let me no how u get on
