While spreading some gravel yesterday with my JD655 she started sputtering and spitten and then stalled. So, a long story short, it was out of fuel. Bled the lines, ran pump unhooked from sediment bowl, blew air up line to tank before I found the problem.......my fuel gauge showed about 3/8ths full. First time this happened. Do I need a new sender? Fuel gauge goes done to zero when key off and back to 3/8 when on. Or do I just fill it up when it shows half a tank, which now means empty. Heck, I wasted a cup of fuel trying to bleed empty lines and the stuff is like liquid gold nowdays!
