Does anyone have any pics of the duramax fuel cooler? I'm thinking of retrofitting one to my 6.5 truck and wondering if it's feasible.

Also, do all years of dmax trucks have one? And last, could a cooler originally used for engine/trans oil be used or would it not be compatible with diesel fuel? I know flex-a-lite sells a fuel cooler with cooper lines but do not recommend it for diesel use, only gas.

Thanks in advance. Joe.
