The last thing on my maintenance list was changing the fuel filter. Old diesels require bleeding the air out of the fuel lines whenever the filter is changed but that isn't necessary with my Sprinter. Mercedes-Benz says I should change the fuel filter with every oil change at 10K miles. Many don't think that is really necessary and change them every other oil change. Since I have no idea when it was last changed, if ever, I thought it prudent to put in a new one.

All the things on the old filter had to be removed and put onto the new filter. The base has a plastic ring that I had to remove and place on the new filter. It holds the filter in the right position in the bracket. The exit hose had the fuel injector clamp and the hose on the center appears to be an air hose but was broken. The other piece was on the clamp on the exit hose. I replaced it later.

I double checked that everything was tight and done. Cleared off my tools and started the engine. I held the key at position 2 for about 40 seconds, then to ignition and it started right up. Nice.
I completed this job Friday afternoon and took it for a spin to be sure it worked. And it did. I saved myself several hundred dollars doing it myself. It took longer than it should have, probably because at least some of it hadn't been done maybe ever so getting things loose took awhile and several tool changes to find something that worked. But I got it done. And now I know how. Next time, it should go easier. I feel very accomplished.
