CAV filters and 100 series

What type of fuel pump did you use

thanks Lucy, photos worked good!
I'll go and borrow a filter setup tomorrow and see where and how it can be fitted.
Cheers everyone!

For info - my 1981 Peugeot diesel car has a CAV filter fitted from new and the recommended replacement interval is 20,000 kms.

As a matter of interest has anyone found a way of fitting a water indicator to a CAV?
My Humvee only has the CAV agglerometer fitted, filter at the top and glass bowl at the bottom, no physical indication if water is present like the standard Toyota setup.
Years ago I was advised by a diesel engineer to plumb the CAV agglerometer in the reverse direction to the arrows on the top casting. If plumbed according to the arrows then the crap is caught by the filter element and only clear fuel is in the bowl, if you plumb it in the reverse direction the crap ends up in the bowl and the filter element lasts much longer.

Have a look at the site link I posted above and you will see there is TWO items in my CAV setup.

(a) Agglomerator - which is brings the fuel in at the top and then down over a serrated cone which forms it into a very thin layer seperating water and any other solid chit from the fuel.

It the drops off the outer edge of the 'cone with the heavier than fuel (water & solids) chit dropping to the bottom of the glass bowl and the fuel exiting the unit up the centre of same in to item (b)

(b) Fuel filter - fuel comes from agglomerator into top/center of fuel filter unit, down through the filter cartridge into the bottom of the glass bowl and up the centre, pipe and out to the pump.

In both units you get to see the crud in the bowls.

Now as to the water sensor - I have never seen a CAV unit with one.

There may be some other electronic after market gizmo available that would fit into the fuel line pre filter pack that would give you a heads up on the water in the fuel issue. You now have me thinking about this aspect.

Yes I looked at yours before I posted, the agglerometer that I have has the diecast top like yours, a 296 filter element and then a glass bowl the same size as the filter with a diecast base with the drain cock.
You can actually replace the bowl with a second filter element if you desire.
But back to the top casting, if you follow the arrows for the connections the fuel goes through the filter and then into the bowl which is arse about as only clean fuel ends up in the bowl and all the crud in the filter.
Plumbing it in the opposite direction on my unit puts the fuel down through the centre into the bowl and then back up through the filter and on to the engine. This allows most of the crud and water to stay in the bowl with the filter picking up the finer stuff.
Funnily enough I have a very old Brass CAV setup which has the arrows in the 'correct' direction.
I tried using a water sedimenter bowl (which has a float switch in it ) from a 40 series cruiser upstream of the CAV but it was too much of a restriction to fuel flow which nobbled the performance.
