After having been towed in, changing fuel lines, filters and clamps, draining float bowls and adjusting pilot screws to no avail, I removed the sending unit and began to remove fuel into a clear container for inspection. I found that the fuel had seperated into two layers - neither one of them good. I visited the internet where I learned about the cause of seperation. What I didn't learn was how to deal with it in the future. Can anyone help me? I have a 45 gallon tank. The tank is vented to the outside. I only add fuel stabilizer in the winter. I am afraid to fill the tank with fuel only to drain $250.00 in fuel and throw it away. What should be my best course of action?
