OK, this really shouldn't be that hard, but I'm stumped. I can't figure when the return line goes to on the heater hose. The TPI has a hose that fits on the intake and runs to the throttle body and then to the heater core. I'll more than likely bypass the throttle body as I was informed that I could gain some extra power, so It will run directly into the heater core. The problem is that I don't see any place to hook up the return line. I know that it's usually on the water pump but this one has nothing. Anybody else out there with a TPI swap that can fill me in?
