Appreciate the replys. My neighbor who installed the lines is out of town, so no feedback on why couldn't trace fuel line to correct input. He's no novice though, so must be a reason. I was hoping to eliminate having to buy $100 + in gas to find out, but think that'll be the easiest solution. Once I get the floorboard, etc all cleaned up, I'll get new markings on for sure. Will also remember Johntsmith's advice on changing over tanks each refill! Good advice and appreciate it.
