Default Diesel fuel overheating

Our recently acquired Jeep Grand Cherokee Limited MY13 died twice on us after towing a lightly loaded horse float for about 6 hours. Thank heavens no horses on board! Jeep Dubbo didn't find anything wrong with it. Moree NMRA guy diagnosed overheated diesel fuel which affects the "suction control valve". Advised to drive with as full a tank as possible to prevent overheating. We can't demonstrate the problem to Jeep Southport QLD and they refuse to change suction valve. Has anyone got a suggestion to keep fuel cool or is this a common problem. Any "fuel coolers" which can be installed?
Otherwise very comfy car but miss our 22 year old Grand Cherokee petrol..

Default Diesel fuel overheating

I own MY13 Grand Cherokee Diesel and sometimes have driven in hot weather towing caravan, fuel tank fairy empty ( light showing) no problem thank god, but will keep in mind to keep fuel filled up no matter what the price is at the pump.

The WJ 2.7 CRD has a return line fuel cooler mounted under the floor under rear LH passenger seat, IMO I would get one of those and retro fit it to your vehicle.
