Those things are grossly over priced (last time I looked) and I don't think they'll benefit the 123 car or any Mercedes Diesel for that matter...

Shouldn't be a big deal, might go in place of the windshield washer tank? I'd remove the stock lift pump from the side of the IP and fabricate a plate and gasket to cover the hole (remember to fill it back up with oil!).

EDIT: also take advantage of the increased fuel pressure by installing either a higher-pressure bleed off bolt on the back of the IP or a fuel pressure regulator after the stock banjo bolt.

ok I looked at the site- now the first ?--- why? what does it do for your MB diesel?

My cars have been operating just fine without that

The cheapest one is $530 for what amounts to an electric gerotor fuel pump and two filters. No way is it worth that.

If you really want one, put it on your Powerstroke where it'll actually do some good... :)

Agreed. However, it might be worth looking into getting more pressure and less pulsation to the IP somehow.

There are lots of sub-$100 pumps. Ford's Powerchoke uses an electric pump that would do the job very well.

They do it alot on cummins engines with mechanical lift pumps mainly to purge the air out of the system. The micro air that doesnt get purged normally out of the system.
