RE: Fuel filter location

[Aleksander Mierzwa <alex@matrix.com.pl>]

I can't speak for the 100, but on the 5K it is an easy job.
One of the fuel lines was very tight on the old filter, but that was the
only problem. Fuel system can be depressurized by several methods
(running the engine with fuel pump disconnected, applying voltage to one
of the injectors). I don't know which one is applicable to V6s with
Motronic, on the CIS systems the easiest method is to loose one of the
lines at the warm up regulator (don't remember which one now, it's
documented in Haynes). I didn't have any leaks although I did not
replace the gaskets (that's stupid, very stupid, I know it, Phil :-)
