Volks,

I’ve recently upgraded my TriStar to use a pumpe düse TDI engine. This flavour of the TDI uses the cam to push on the injector to make some REALLY high fuel pressures for better economy and pollution levels. The draw back of this is that the injector doesn’t squirt all of this compressed fuel and most of it gets returned to the tank. As we are aware, when you compress something it gets hot and Diesel fuel is no exception to that rule. After a 30 minute drive the fuel in the return line is almost as hot as the coolant! As a result of this VW / Audi fits a small radiator to the fuel return line to cool the fuel off before it goes to the tank. I have a small 4 x 12” oil cooler that I am using for a fuel cooler and it is mounted on the very back wall of the engine compartment so it is just visible if you look up into the engine compartment from below. Well, that cooler is damn hot! The fuel between the cooler and the tank is definitely cooler than the pre cooler fuel, but I would like to get it colder. Besides running the fuel return line to the front of the van and to the back again ( I have a Syncro ) is there any other place that people have used for oil coolers that won’t get hit with road and off-road debris and still get plenty of air going over it? I was thinking of the area under the sliding door.

Pictures of the install (including the fuel cooler’s present location) can be seen at http://www.hasenwerk.ca/pumpedusetristar

Thanks in advance!
