This is my "fuel cooler"
Fuel goes in the bottom fitting, out the top fitting, in my water injection tank is a allow fuel coil, it stabilizes the fuel temperature, after a 30 minute drive the tank is still cold to touch, I have included a log of the fuel temperature on a highlighted 3rd gear 100kmh to 150kmh run in 2.291 seconds! 20 deg C ambient day yesterday at this test run.
Fact V's Fiction lol
