Marine stuff and industrial diesel stuff tends to have a section at the bottom of the filter without any medium in it, or a dedicated water seperator with a metal screen and space for water to accumulate.

The mb filters have a small section at the bottom, but it's much smaller than the marine equivalent.

I do think Robbie could do with a definitive list and sequence of things he needs to do now to get up and running. The danger is going round and round in circles spending money replacing filters only to have to replace them again if the sequence of jobs isn't right. So anyone want to volunteer a list / sequence ?

I'd have questions like, how much injected crap is in each cylinder now from the contaminated fuel and does it need sucking out or will it vaporise fairly quickly when the engine starts? - is it worth getting some easy start to help things along? As its a saddle tank how do you ensure all the watery fuel is out from both sides of the tank? Is he better off with 1/2 tank plus of fuel if the fuel system will be empty from draining it all down - to ensure there is fuel both sides of the saddle..

Remove sample of fuel from tank, if its milky, drain tank and re-fill with fresh diesel.

Once the tank has good clean fuel in it, disconnect the supply side of the fuel pipe from the fuel filter, and direct into a container.

turn key to pos 2 and let the lift pump empty the lines etc from the tank, until you have clean diesel flowing out of the pipe.

If you do not have an in tank lift pump, you will need to use an oil sucker (pela extra etc) to suck the diesel from this line.

When you have clean diesel coming out of this pipe, fit new filter and bleed (by either cranking for a long time, or sucking fuel from the "out" port of the fuel filter using said sucker.)

Re-connect fuel pipes up and crank for 15-20 seconds at a time until it fires.

Thank you. Much much appreciated

... although bear in mind that an additive such as the good one shown above, will not rid the tank of water.
That additive is for the future - it won't fix your milky diesel problem.

To fix that, you need to get the tank clean and filled with fresh diesel.
Afterwards is the right moment to add Marine 16 (or any of several similar additives that combat 'diesel bug').

Right. Okay. Question. Is there any possible way for any kind of water Or moisture to find its way back into the fuel tank from the engine. Bearing in mind that I have been cleaning the engine bay with some hoses removed using a karcher. Including the inlet manifold which was caked in oil and carbon from the turbo blow out. I used a degreaser solution to break down the mess in the manifold and then rinsed it out using the karcher. Could this have some how got back to the tank? But if so how?

Another update. We now believe after doing a bit of chemistry beside the car that the white stuff is in fact degreaser. When mixed with diesel it turns white.
And we did attempt to fire her up as we had drained quite a bit out via the entry to the fuel filter however it seems not to be enough. So I will continue draining more off And the battery needs a rest and recharge. IMG_6079.JPG be9ec686-4826-4f51-af1f-941315aa0310.jpg

Ah ... again! This is fresh information. You enjoy springing surprises, don't you!

It is possible that if fuel supply hoses in the engine bay were disconnected and with exposed ends, some degreaser could have got into the hoses under pressure washing. Makes me wonder what else might have been hit with the pressure washer that hasn't shown up yet. When was this pressure washing in the engine bay done?

It makes little difference to your course of action though. You'll still need to clean out the tank and fuel lines before you can confidently drive away.

You know what? I am getting a bit fed up of these surprises myself. I was expecting to be driving her to Halfords for the Mot by now. As in the one on offer after buying loads of stuff from them earlier this year.
So, how the heck do I now flush through and clean out the fuel system? And now I am wondering what has happened to the injectors with this stuff going through them?!!
I believe I have drained as much as is possible given the fact that the car is on a very slight small incline with the engine upper most.
So, what is the best way now to ‘flush’ through and clean out the fuel system?

For future reference never jetwash an engine. The risk of water getting somewhere it shouldn't is too high. Most seals are only designed to resist a little over atmospheric pressures.
Now you've drained the tank fill with 20 litres of fuel. Then with the feed to the high pressure pump disconnected and with a suitable container to catch fuel turn on the ignition. The pump in the tank should run a few seconds then switch off. Repeat until clean diesel comes out.
Reconnect the feed line.
At this point you can try starting it. There will be air in the system so it will take a lot of cranking to release it. Only do short bursts of cranking allowing a minute or so between each attempt. You can optionally try squirting easy start into the inlet tract (with the air cleaner removed squirt it in the inlet tract while someone else cranks). Just short bursts.

Engine sounds low on compression still.

Your injector seals are also leaking unfortunately, I can definitely see number 1 puffing away, not sure on the rest, if they are all leaking badly, it will never start....
