AF thanks - I’m too lazy to do all the typing
Sorry I see I jumped in before you’d finished your message on the marine stuff.... note to self, be patientAh ... got it. Thanks.
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.
Given you have had water in the fuel I would also add some of this:

Water in the tank can promote algae growth and given yours has sat for some time there's a chance it could be present.
If it is a good biocide will break it down.
Yes correct.... 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').
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.
