This all metal cleanable 60 micron filter can be the answer for many Mercedes 220D 240D 300D 300CD 300TD 300SD / SDL and 190D diesel engine applications. If you are tired of always spending money to replace your plastic pre-filters then here is your answer. If you would like an inline filter when doing your diesel purges to prevent crude from re-entering the injection pump this is the ideal solution. If you need a final filter to protect your injection pump when running waste vegetable oil this is it!

Filter should be installed just before the inlet to the injection pump. Hi temp hose included is required if running heated SVO.

Mercedes Late 617 Turbo Main Fuel Filter Bolt O-ring Seals x 2

Only fits some late 1984 some 1985 models - Requires inspection of existing bolt!

Item: DSL-COMLFBOR
$3.25

For reasons of hoping to solve fuel filter leak problems Mercedes changed the center bolt design in some 1984 to 1985 model 123 300D 300TD 300CD and 126 300SD. Instead of one o-ring on the bolt they changed it to two orings (as shown iin the picture. Problem is it is not possible to determine which bolt you have unless you remove it. A copper or aluminum washer under the head of the bolt will give you a clue you may have an older bolt design - but not for sure! I have seen some actually place a washer under the head of the bolt that has two o-rings (and this is not necessary)! The larger o-ring is particularly hard to find.

Mercedes Restoration Article: 1982 Mercedes 123 300D

My goal was to find a 1982 to 1984 300D sedan in good solid condition. I personally feel this is the best of the breed.  (Note: I try to avoid the 1985 models with the trap oxidizer). It had to have absolutely no rust or accident damage and under 250,000 total chassis miles. From my experience of working on hundreds of 123 chassis I have learned that a Mercedes exposed to road salt is just not worth dealing with and one with more than 250,000 miles may leave you fixing many more things than you ever imagined. I was not afraid of an engine transplant as I had a good low mileage engine as well as a completely rebuilt 617 turbo hiding away in my shop. A good color combination was highly desirable
