So what should you expect to find in your fuel filter? Was not running so hot at the last races, mostly idle issues. Anyway I drained the tanks, flushed the system, and changed fuel filter element. The canister bowl, had a fare amount of sand, carb bowls had a teaspoon of water. I cut the element apart, and found a little more sand, but not what I was expecting. My fuel jugs are clean, I fill 5 gallons at a time, so the whole container goes in. this is the first time in a while, I've had water issues, but the sand is bothering.
