[diesel_mercedes] Weepy Fuel Filter Fix

 

O.K. Brian ;

Here's the deal : the early typ has an aluminum crush washer under the 22MM head of the banjo bolt , this often leaks or weeps .

Wipe the oily dirt off the filter head and look at the part # ~ if it reads : 615 092 01 08 , it's the early typ  that uses the aluminum crush washer and IMO should be replaced with the 1983 > filter head P/N 615 092 02 08 , this one uses the two O-Rings in the banjo bolt , replace them before using it .

Some times you'll find an older 01 head with an aluminum crush washer , if so remove the washer and replace both O-Rings , you should be good to go .

These later fuel filter heads are a direct BOLT IN replacement for all 1977 ~ 1985 W-123's and W-126's , both OM616 (four cylinder) and OM617 (five cylinder) versions , maybe later models too , I have not checked .

I have a weepy fuel filter too, not enough to get too excited about, but would be interested in hearing about your fix.

"I also found  and purchased two fuel filter heads of the late model typ that have two O-Rings on the 22MM ATF bolt , this change was made because the early typ used one O-Ring and a large aluminum flat washer right under the banjo bolt's head , these tend to weep Diesel fuel after you change the filter."
