Fuel Cooler needed?

HI I am repowering my 94 gmc with a duramax and wanted some advice on weather i need to fit a fuel cooler to the return line like in the 2001 models and later. i live on the coast in southern victoria australia . i am also trying to find out about companys in your country who convert gmcs to right hand drive because i need a wiring harness to suit right hand drive . i have a wiring harness from a 2004 model but needs extending about 4 feet . it will be a big job to extend only to find out later a suitable one could be purchased thanks andrew mccosh [ twitsinc ]

I didn't install a fuel cooler in my Duramax conversion, but.... I would have if this truck would be used to tow or work. I may yet install one regardless.

Somewhere here in the board is a photo sequence showing a 200x Duramax powered truck being converted to RHD by a member in Australia. It was a few years ago. A search for the appropriate keywords should find it.
