Fuel Filters

Vinnie,
I have run the Racor finer fuel filter (R26T) in both my GQ's. My 1989 had one fitted when i bought the vehicle. When i sold the vehicle I removed the Racor and fitted it onto my 1994 GQ. I change the filter every 40,000 kms. Have done from day 1.

I can honestly say that on a few occasions I have opened the old filter up to see just whats inside it. The worst I ever came across was over 1/2 full of crap, but i know that on that occasion i got myself a bad tank of fuel a week before. All other used filters I have opened up were around 1/4 to just under 1/2 crapped out. I am seriously thinking of taking my next filter to 50,000 before replacing it.
I also carry a spare in car just incase something unexpected happens.

I also have the CAV setup which came with my present GQ when i purchased the vehicle. It was the first thing I removed once the GQ was home for its first time in my driveway. What i dont like about the CAV is the fact that they tend to leak fuel around the "O" ring that sits on the bottom bowl. Although the Racor filter costs more (approx 45.00 each), I believe it filters better than the CAV and is a much stronger setup. Thats just my opinion ok.

Vinnie,

There are the lucky ones who seldom have problems, and the two of us.
Every trip I seem to pick up a load of dirty diesel somewhere :-(.

Around Brisy, have settled on one place that doesn't seem too bad. Local Brisbane refined fuel.
Was using Woolworths fuel, but had too many problems with dirt. Now they are using Caltex, it may be better.

Sometimes I have had to change filters every 5000. Ended up flushing the tank.
Had sand, hair, rust and water.

I always try and buy fuel at major truck stops on the road, but sometimes you have no choice at small local towns.

My Pajero only has the one filter, but a reasonably good stock one. have since put in a second filter off a 60 series LC. Cheaper to buy and easier to change. Got to watch I don't cause too much resistance in the line for the fuel pump though.

Did hear you can get a sock to go in the filler, but it would take for ever to fill the tank (135l).

You may have fungi or bacteria growing in your tank. A tank drain to get any water out and a biocide may keep your filters claener. There are many biocides available to kill/stop bugs growing in your fuel and most also claim to increase the lubricity of the fuel. There is some useful info at www.fueldoctor.com.au or just google "diesel biocide". Have been running morey's, fuel doctor and others depending on availability when I run out and have had no filter probs touch wood.
