After reading some of the horror stories in CT regarding catastrophic engine failures caused by dirty fuel, I have decided to fit a Stanadyne Fuel Manager (FM100) system to my 2012 T3 V6 TDI.
I have searched this forum as well as myTreg (UK), but cannot find anyone who has already installed a pre-filter, so this is all a matter of trial and error for me. The most difficult part so far has been finding a location in the engine bay to install the filter, and then design a bracket to hold the filter in a vertical position. I now have that sorted, and will soon post some photos in case anyone wants to do the same.
My local Diesel shop has never worked on a Touareg, and is a bit unsure about some matters. The current question I have is as follows;
Every time the drivers door is opened, the rear fuel pump starts up for a few seconds and primes the fuel system. Does this mean that when they take a fuel line off the OEM filter, the rear fuel pump will detect that the system needs to be reprimed, and so start pumping fuel out of the fuel line? Obviously this cannot be allowed to happen, but how do they turn off the rear pump? I searched the online documents downloaded from CT, and found the section that describes how to change the fuel filter in a diesel T3. But it starts at the step of removing the 5 bolts at the top of the filter, so obviously they have already stopped the rear pump from operating. Surely its not simply a matter of NOT opening the drivers door??? So, has anybody successfully changed their fuel filter, without covering the garage floor with diesel?
