'98 E300TD fuel filter o-rings

[jwasbury]

Hi folks,

The Mann Filter secondary fuel filter came with 2 small o-rings, one smaller than the other. One of them obviously goes in a groove on the banjo bolt. Not so obvious where the other goes. The old filter I removed had a plastic piece that sat on top of the filter and had a rubber seal of sorts. The replacement didnt have that plastic gizmo.

Any help appreciated.
