WELL YOU KNOW THERE ISNT A PROBLEM WITH THE ENGINE OR PLUMBING FROM YOU TANK SELECTOR VALVE CORRECT? IF SO, THE PROBLEM IS ASSOCIATED WITH ONE TANK. THE SILICONE IS PROBABLY CLOGGED IN THE HOSE FROM THE TANK TO THE SELECTOR OR IN THE SELECTOR VALVE NIPPLE. TRY TO BLOW BACK INTO THE TANK THROUGH THE PICKUP TUBE TO BE SURE THERE ISNT ANYMORE "BLUE GOO". OBVIOUSLY IM ASSUMING YOU HAVE TWO BUILT IN TANKS WITH A SELECTOR VALVE AS I DO. ALSO CHECK ALL CONNECTIONS AS YOU MAY BE SUCKING AIR SOMEWHERE. TRASH ALL RUSTED/CORRODED HOSE CLAMPS AND REPLACE WITH STAINLESS. AT LEAST YOU HAVE THE PROBLEM ISOLATED. MAYBE A PIN HOLE IN THE PICKUP TUBE ABOVE THE FUEL LEVEL. JUST THINKING AS I WRITE.
