Diesel fuel contamination

Whats the additive and how can it counteract something where the contaminant is of a granular nature (i.e. dirt not water). The problem seems to be that the new common rail diesels, with their very close injector tolerances, are very susceptible to any foriegn matter in fuel and so extra filtration seems to be the safe way to go.

Agree, but I use old technology.

Tks Roachie. Have had a lok at the site and it looks promising. Have you used stuff from these bods?
On another front- I have about 100 liters of diesel in a clean drum which has been sitting for 3 mths in a cool place. Do you thing it might have started to grow'bugs' (biological, not dirt) Years ago diesel grew "black clag' but I think that they now add something to it, to stop this.You'd think that if this was happening then the drums that they deliver to Well 23 CSR from the Mt Newman roadhouse would be petty toxic after sitting in the hot sun for two months

Sorry Doug T
That lok was meant to be "look"

My understanding is that these bugs tend to grow when there is a bit of space in the tank (or drum), which engenders moisture build-up on the sides of the tank (or drum).

If the tank is practically full, then there is not as much liklihood of the organisms flourishing......they actually grow in between the invisible layer between the diesel and water. Or something like that.

It is for this reason that I always try to keep both my diesel tanks full. A lot of blokes only ever put fuel in their sub tank when they are about to go on a long trip, thinking they are doing themselves a favour by not carting a lot of extra fuel around unnecessarily most of the time. I think this is not such a good idea....but I have no proof; it's just what I've read over the years.

The DeBug unit is simple....it just has 3 large, powerful magnets inside which are separated by plastic spacers. Any "dirt" would sink to the bottom of the bowl and be very unlikely to get through to the filter/s

Tks roachie. To clarify. Are you asying that the magnets pick up any metallic stuff and the other crud just sinks to the bottom and that way all bases are covered? Did you get one of these units and how hard to fit.

I have one, sitting in the shed ATM......I haven't got around to fitting it yet.

Easy to fit, so long as you've got the space. They take up about the same area as a standard filter arrangement.

Simply arrange for the hose that goes to the filter, to go to the DeBug's "in port", then from it's "out port" to the filter's "in port".

I haven't got any space under the bonnet, but will eventually put it down the back near the tank, under the tray.....plenty of room under there.

Yes, that's what I reckon happens.....metals and algae etc are treated by the magnets....other sediments sink to the bottom of the bowl. It has a drain bung.

Wigger,
I could not find that thread . What was the subject?

By the sounds of it , it was dirt and not water.

A daily inspection of unit , which is clear would show the dirt at bottom , and it can be drained quite simply.

If too dirty then other drastic action needs to be taken, but it could be taken before any damage.

At least it can be seen, rather than hidden as it obviously was.

Sorry Should have given you more info
Go to WWW.4wdmonthly.com
Go to Forum
Go to the 3rd categorycalled "tech talk"
Go to last category-"other makes"
Go to the post from 'artic wolf' (5th one down)

There are two pages on this saga

Why not? is there too much resistance for the pump to cope with?

Tks Peter, To take up point on last line. I presume you are talking about the bypass filter on your wife's car being an oil filter so this doesn't solve the problem. In addition, my understanding is that fuel filters have a finer filtration than oil filters because we had a complaint from a guy who bought a 2nd hand tractor which had a BALDWIN fuel filter fitted in place of the correct oil filter. Rang BALDWIN, for replacement no. who said he got good deal and should stop his moaning.This is how i got the idea about finer filtration on fuel filters. This seems to be a very tricky subject and might need some expert advice before adding a second filter.
If you read the 4wd forum post you come away thinking that you'd better make sure it doesn't happen to you . Guy insists that he bought diesel from big s/stations up at Nerang.

Tks pedro,
Can you let me know how you get on with the new filter/trap and whether you do see black clag or water in your fuel. It would be interesting to know what the quality of the 'discount' fuel being sold by Coles and C/WWs is like and you've now got the piece of gear to find out. What date was the GC bulletin featuring the article?
