I'm sorry but you are wrong at least for the A1000. If you run the pump at full speed continuously you are creating unnecessary heat to dissipate. That's the whole idea for the pump controller... to modulate the speed of the pump according to demand. Possibly a good reason for the OP pump failure (if he isn't running the Aeromotive controller for that pump)
Hey whatever... I'm just saying how I installed mine and what works for me. And... I do have a return line back to the tank. Below is from the Aeromotive website.
