Depends on the 6.5
There's one O-ring at the fuel heater -bottom of fuel filter manager- and a small one at the water in fuel sensor.
One the upper part, one O-ring is coming with each filter.
The screen goes on the inner tube.
Thanks.
So large one at bottom for heater, small one for WIF sensor, and the one that comes with the filter.
So 3.
Now the WIF one, that sits behind the 2 screws plate?
