Had the long range tanks in my GU CRD Patrol repaired after smashing them both on some rocks. The workshop had flushed them with water prior to welding and then tested them for leaks with water prior to refitting, I’ve done a couple of hundred kms since I got it back and yesterday on the way home the water in fuel warning light came on.
I drained the filter water out and then disconnected and pumped the primer, the stuff that came out was almost like milk! They obviously haven’t flushed the tanks well enough!
Hoping the factory filter did its job prior to any fuel pump/injector issues, as I had no other issues apart from the warning light coming on. I gave them a call this morning and they sent a tow truck over to get it back to them. Talk about steam coming out my ears when I saw the fuel.
Bit late now, but may save me in the future, but I’ve got a fuel manager pre-filter with water alarm and optional primer on the way.
The shot glass in the pic shows what I drained from the filter trap, looks like nearly pure water. The plastic jug is what’s coming out when I pump the primer!
Tis' the way of this world it seems these days unfortunately. Trades and proper trade practices have gone out the window and people just don't give a f$#k anymore. Get the job done and as quick as possible and onto the next job.

Yep, I wouldn’t have thought draining and cleaning a tank prior to re-installing it would be a hard task. Pretty disappointed and now worried about any further damage to the injection system.

Yep. I'd be concerned. Keep everything documented and all contact with the mechanics via email so theres a "paper trail". The world has grown into one massive place of incompetence.

The concern with CRD is that the fuel rail pressure / fuel pump can see high pressure >160MPa (23000-25000psi) @ full load. As you cannot compress water, this condition can strip minute particles of metal off the pump plungers (damage) and stuff injectors.
You can take a sample of the contaminated fuel (store some anyway for latter reference) and place it in a small glass tube (say 10mm dia x 30mm depth) and shine a UV pen light light up thru the water column from underneath and if metal particles are present you will see them as bright glitter. Hopefully you caught it early.
I had CRD fuel pump failure couple of years ago and as a precautionary measure installed a WaterWatch pre filter (supplied by Responsive Engineering -Cooma Diesel). Something to consider as well. Give Responsive Engineering/Cooma Diesel 02 62800178 a call _ just more info / knowledge for you to deal with these cowboys.
The tanks were repaired about 2 or 3 weeks ago, and it’s only done around 220km or so since then with no issues. The day before the warning light came on, I’d pumped about 10 or 15 litres from the Aux to the main to ensure the transfer pump was working, so I am suspecting the aux tank was the culprit. Once the warning light came on it was a couple of kms to home, no misfiring or problems at all. So hopefully no further problems.
I’ll be having a chat to them tomorrow about my concerns for the longevity of the injection components. I’ve already pulled the trigger on the Fuel manager system c/w alarm. I looked at the water watch system but preferred to go with a unit that filters as well.
I’ve got no hope of mounting the fuel manager where you have yours, as the later CRD’s with rear air have different routing of the air con line. I’ll need to run it from the passenger side, which isn’t ideal.
