Car started running real funny, like the throttle wasn't responding properly, no power on hills and loads of blue smoke on the hills.
Starts on the button.

A couple of weeks ago I changed the fuel filler pipes and as part of this I partially drained the tank, not sure if I've picked up some *beep* at that point or its from a petrol station.

Changed the filter tonight and this is what came out:-

But anyone seen anything like this? And do I drive through it or totally drain the tank?

Cheers

Looks like some dirty fuel from a contaminated tank in a fuel station. For peace of mind it might be worth completely draining the tank and decanting the nasty stuff out before replacing the clean fuel back. It will be always at the back of your mind if you don't.

Looks like a layer of water, did the warning light come on?
I would strain the tank through a water separating filter into jerry cans then filter again till it's clear of the water.
And hope it hasn't done any damage yet.
We're th pipes holed when you took them off?
The other possibility is a bad tank full when you filled up. I used to have to drain my filter when I bought from Tesco, now go to local Independant and haven't had any issues.

The return pipe was rusted right through.

There's definitely 3 different layers?

What's a separation filter and where's the best place to get one.

Tank is 3/4 full of course!

i had this on a blokes shogun sport,so i removed the tank cleaned it all out replaced it along with all new fuel lines and filter...the tank had a bit more *beep* in than that..his had a grey sludge that had blocked up the pick up filter causing lack of power and setting the engine management light off,but since it,s been cleaned it has been fine he reckons it runs better now than it did when he first bought it Wink

I have a funnel with a gauze that stops water, got it for my chainsaws. When I need to mix fuel and also use it filling my boats tank from cans.
There's a few here, must be a separating one you get.

Have you had this paj long?
This will make you laugh but I had a old transit some years back ago.
was a 2.5di on a bosch.
Was looking rough and I ended up putting 500,000 miles on it.
in end as got a new 2 year old citreon relay I use to run the transit on all my waste engine oil plus hydraulic oil.
thats what I found.
the hydraulic oil looked like this.
I use to have milk bottles near my desk.
I use to put the fuels in that I ran on to see why when left it was a funny start, lil knocky until moved.
turned out the hydraulic oil would part.
oh hydraulic oil was to great a start in winter pmsl but as I do plant machinery etc I use to get barrels of the stuff, 45 gal cans.
now its so expensive its just tested and never changed.
I ended up making my daughter a swimming pool heater so I still get rid of oil lol.
im so tight pmsl.

Have just seen pix of your pipe work, mine was the same!
Not surprised you have water in the fuel now.
Hope you got it in time.

That is the residue of vegetable oil, or to be more precise waste veg oil and this clogs up your fuel filter over time, how long have you had the vehicle and did the previous owner run on veg oil?

First drain your tank and sit it in clear plastic drums for a couple of days as this will allow the veg oil sludge and water to settle on the bottom, syphon off the clean diesel and store it in clean containers and add a fuel treatment to it, whip off the top of your tank and pull the fuel pipes and sender assembly out, spray a good degreaser into the tank and flush out with water to clean any remaining debris out, stuff a hair dryer into the top and blow it dry.

Remove the fuel feed and return pipes at the filter and tank, pour in degreaser and let it work; to do this you pour it in at the filter end and catch it at the other end in a container, give it time to work them flush through with water and then an air line to dry it. Replace the pipes and fuel sender assembly and tank bung.

Check the clean fuel and see if anything has settled now it has a fuel treatment in it and if it has then drain the clean fuel again and put the clean fuel back into the tank, add more fuel treatment and prime the fuel system, run the engine with a new fuel filter installed and check everything is fine, then replace the fuel filter at 1000 miles and check for contamination and debris, there should be none; the fuel treatment should clean the pump and injectors and all should be well.

Assassin, interesting. I was running on bio about 5 years ago before wrecking the pump and completely flushing the tank and lines.

As part of all the recent problems of the last few weeks I fitted a glass inline filter, see below, completely blocked, the worrying thing this is after the main filter!

System all drained & flushed, diesel nice and clear. Running sweet now.

These trucks are very forgiving!

Cheers guys.
