Thread: 2.2l fuel filter change

Fair enough beery
I was just assuming it would be like racors etc etc which run down the guts to the water trap then up through the media to outlet

Pure assumption on my behalf haven't changed out the tdci filter yet

Accidental contaminants, hands, funnel, rags, missus mowing the lawn etc. Are you saying there are two filters, only aware of one in the rear wheel arch, 2.2?

Likewise, I haven't changed mine either, so I could be wrong. But the filters Ive seen flow inwards through the media.

Just for some fun I found this flow diagram on the Baldwin site for Dieso filter with water trap.... Obviously whatever LR used on the tdci may in fact be different but this was my understanding of how diesel filter water separators flow...
Assuming this is how the 2.4 tdci flows with a clean funnel pouring Dieso into the centre will mean any contaminates get filtered pre engine anyways ... Same as filtering crud from the main tank.

You'll find the fuel flow depends on the header and element type. There is generally normal and reverse.

Normal flow header has one inlet and one outlet on each side, internally the fuel flows through the centre tube then through the filter media.
Reverse flow header has both inlet ports in the front and both outlet ports in the rear. Internally the fuel flows through the media first, then out through the centre tube.


Filter systems with electric lift pumps must use a reverse flow type system, to ensure fuel is filtered before entering the pump.

I knew I had it somewhere, the computer I had this on died two days ago, but hopefully the link works.

Pages 3 and 15 show some helpful illustrations.

When I first started servicing my 2.4 Puma, I asked Stanadyne, now Clarcor, for some info/specs on their filters, and this is what they sent. Most suppliers of aftermarket service kits seem to use these fuel filters.

Just some more info...

On a Common Rail diesel engine, its not just the fine tolerances of the high pressure fuel pump and the injectors. The fuel pressure on idle is round 3000psi, with max output being round 30,000psi .... (I put that in psi rather than bar, so people get a clearer idea of pressures). So any contaminants are going to make short work of internal components on the high pressure side.

(sort of still on topic)
When all said and done, when traveling remotely...
*if its a 2.4lt u now need to carry a little in line pump (its not just changing the filter, what happens if u get a fuel tank leak, or run out of fuel etc).
*Spare fuel filters should be taken.
*Be mind full of filling up from drums and what contaminants are in it (dirt, water) etc etc.
*Would a 2.4lt be better served with adding a lift pump in the fuel tank like the later 2.2lt (am pondering this).

As per the document a few posts above, it appears you can get the FM100 filter assembly with an integrated electric lift pump.

I'd be interested to know what pressure the lift pump in the 2.2 runs at (or flows at full output so that the correct filter family can be chosen (one specification is how many gallons per hour they need to filter).
