Well I know it won't heat the whole tank up. What I'm wondering is since the return is right beside the pickups, I don't want the same fuel being recycled over and over and heating up. But I'm sure I'm just over thinking it. HaIf it's going to heat up the fuel that much, then after a long drive your whole gas tank is going to nice and toasty:angel:
Seriously though, I'm curious why the return route. I just have a stock fuel pump feeding mine.
