Off-Road Fuel

[luvrbus]

Your XLE should have one between the fuel tank and engine unless somebody removed it never saw a Prevost without one made after 1994.
It looks more like a oversize power steering cooler fwiw you lose 5% HP for every 20 * over 95 degrees  and here in AZ in July with the pavement temps around 140* to 160* that is a bunch about 3 pm every day you can feel the difference in power when the fuel  gets hot



good luck

I would thing that keeping the tank as full as possible would also help then.
