I just changed the engine-mounted fuel filter on my C250TD, and want to know if I've made a mistake.
The replacement Mahle filter contained two o-rings, one small and one very small. The Haynes manual showed two o-rings as well.
However only one was present on the fuel filter banjo joint when I took it apart, so I never installed the second o-ring. Car runs fine.
Anyone know if there was a design change in the fuel filter head on the later 606/605 engines?
