Sorry for the dumb question, but how do these "return" setups work and is it worth adding on a 65' tri power that did not have one originally ? Also, power wise, is 3/8 really going to do anything over 5/16 ?
I know on fuel injected, high pressure lines, we like to have looped fuel rails and returns to improve flow, but I can't figure out how this would be configured on a tri power. Thanks
