Bought my TT with an empty fuel cell. Filled with fresh gas. Used 1/4 running the gen. Then, we took our first trip with it and I topped it off to full 30 gallons. The 1st fueling of it pumped orange fuel for about 1/2 gallon. It didn't seem to matter to my ATV. Subsequent fuel-lings still resulted in orange fuel for a few seconds, but then clears up. I did put a tad bit of red stabilizer in the fuel the week prior, but only a few ounces. Why orange?
