Sedimenter Question

Over the weekend I pulled apart and cleaned my sedimenter (the NRC9708 type), mostly because I snapped off that stupid plastic drain plug. In the process I noticed that there was nothing inside besides the diesel and some gunk. Am I correct in thinking there's supposed to be some sort of plastic cone in there to force the actual separation process?

Looks like it does have a piece between the two seals

Yes there is suppose to be an inverted cone at the top of the open space.
This cone prevents fuel from going in the inlet and straight out the outlet.

The inverted cone forces the fuel down where water and particulate are deposited.
The cleaner fuel then flows upward around the edge of the cone and out.

I actually build sedimenters with metal drain screws that don't break off when you try and unscrew or tighten them.
We supply an all metal model and one with a see thru glass that mounts on the inside of the frame rail.
They are a little more expensive, but much better quality that OEM and have Viton seals.

I thought so, anyone know where I can procure a new cone? I'm hoping to to avoid having to buy a whole new sedimenter since there are many other bits and pieces requiring funding as well.

Not all cones for the CAV units are interchangeable.
I have new plastic take out cones and metal thumb screws, but no guarantee the cone will fit your sedimenter.

I use to remove the plastic cones and replace them with aluminum ones when I added heat exchangers for use with WVO, but now build my own higher quality sedimenters.
