The tank will be a bigger heat sink but you can also do this by running the return back to the filter/water separator. Merc did the same with their Cool Fuel set-up (Cool Fuel should not be confused with VST - VST is problematic at best).

Here’s 1. I think they make/sell 2 different ones.

Thank you all for your input, awesome team of experts! I will send a line back to the tank with the proposed fitting.
