I don't know, people run into a lot of theoretical problems that may or not may be a problem in the real world. Some manufacturer actually recommend the return line on top of the tank, others suggest brazing a bung in the neck. I know that using the return bung on the stock tank works fine for me. But my truck is build for towing, probably if will have a different effect if I was going after speed, crazy HP, boost, etc? If I ever run into any issues I will post it on here.

I just wonder how many times their fuel being pushed back in the tank? Does it do it when slowing down or letting the throttle go? I personally would rather have it spraying on the top then from the button and pushing bubbles in the gas. Sorry, I am just thinking out loud.
