Thought I'd pass on how I changed the fuel filter on my 940 in case it helped anyone. I was changing the center support bearing and since it was up on jackstands, I decided it was a good time to change the fuel filter. This was my first fuel filter change on this car but I had done several on 240s. The first thing I noticed was that it only had a banjo fitting on one end. The other end was a combination of several fittings that went straight into the end of the filter. I couldn't see anything that would let me turn the line side without twisting it so I would need to hold the line while rotating the filter. Everything was pretty rusted up and corroded which indicated the need to proceed with caution. The filter was pretty loose within the bracket, it turned easily.

I previously had figured out that an impact wrench was a great tool for loosening the fittings on the 240. I was able to get an impact wrench onto the front banjo fitting with an extension and knuckle. I put on open end wrench on the line on the back. Banjo bolt spun out nicely. Then I went to a bigger socket that fit the shoulder on the filter and used it to loosen the filter from the line on the back end. Reassembly was the reverse....

Impact wrench save the day on this.
