Will the cooler actually cool the fuel? Or will it heat it? The fuel bowls on my carb tend to get a little frosty after some hard running. I know of a boat that has triple 525/whipples and they actually used a heated fuel line on it cause the lines were freezing up.

it's my understanding that fuel coolers were introduced because of the "closed loop" fuel return system to the filter or regulator and not returning to tank, or having no return. By looping the fuel it would return warmed fuel and then loop it again, causing gradual increase temp on fuel. I would assume varying fuel temp can alter the dynamics on afr. returning fuel to tank, or always having a fresh supply such as a carb setup wouldn't need a fuel cooloing system. I am sure there is a brainiac on the forum that can tell us the optimum fuel temp. Too cold, I would assume impacts fuel atomization, too hot probably causes something as well. but then, i am guessing!

Kind of shocked me.
