Thanks for the replies. Let me go try the short bursts of air. Went fishing again this past weekend. Took 15 min to get 4 gallons in. First 1.2 gallons went in good while pulling gas nozzle as slow flow as I could. Fuel gauge is still pegged. Only one tank I think BCB to the best of my knowledge. Only one fuel fill. On the dash, switching from left to right tank makes gauge to straight to zero. Always has. So most likely one tank.
