George can confirm, but looks like the fuel cooler. In the return line from engine back to fuel tank. A very good idea. I did that on our 1993 U240 as well. Made a cover for it for wintertime driving so it would not over-cool the fuel.
To see if it would help, after driving on a hot day with under 1/2 a tank of fuel, put your hand on the tank. Shouldn't even need an IR gauge to see if it is over-hot.
