leaky main fuel filter

It's a German filter insert...this is NOT a spin-on filter (I think MB started using spin-ons with the 123 model)
...the leak is coming from the bolt that you tighten to hold the top of the filter housing to the bottom of the housing.

Will rubber o-rings on either side of the metal sealing ring do the trick...or is the pressure in the fuel system too much for o-rings there?
