I ran the car out of gas on the Power Tour. I dropped the tank later this summer and checked it out, wondering why it wouldn't pick up gas when there was several gallons left. The sock/pickup was on the bottom, but the return hardline came back into the tank parallel to the pump/pickup. It was pointing directly at the bottom of the tank, between 1" to 1.5" to the side of the sock. I suspect what happened was once the level got pretty low, the returning gas was cavitating what was already in the tank. I took a tubing bender and turned and return hardline so it no longer pointed at the bottom of the tank and away from the sock. I haven't had a problem since, but I've been really careful about not getting really low on gas and always keeping an eye on the fuel pressure gauge.
