    Have you got another vehicle? Can you afford to take it off the road for a while? Coz if you do, I would recommend pulling the pump down yourself. I have absolutely no faith that a diesel pump mechanic will not lie to you and feed you a complete crock of crap. I firmly believe all you need is a good workshop manual for the pump, a good set of basic tools (pullers, calipers, etc) some ingenuity and a healthy dose of '$&@? it, I'm gunna fix this myself', and you will find the problem. Those pump shops don't posses some aincient esoteric wisdom, or black magic spell book. They pull it apart, take a look at the shafts, bearings and journals, take a few measurements, replace some worn bits, put it all back together and charge you like you have just been punched in the mouth by man mountain with a fist full of 2 dollar coins.

    I am a bit disenchanted by specialist mechanics. You probably picked up in that though.
    Regards,

    Cade I know what you mean, I am a great believer in doing it myself, at least you know whats been done. Just getting the enthusiasm thats the problem. Its an old car and I have abused it for ages .... I have thought about replacing it with another pump, but I guess you could just be going from one dud to another.
    Where do you get the manual for a specific pump?? I have fitted an o ring on it years ago and I know I could get it off ok. I would not pay to have it repaire dthe car is just not worth spending that kind of money on, its a bit of a roughie. I see your in Brisbane too , do you blend or make bio?

    Art you will probably need to pull the pump apart. There is a VW forum thread which explains it all with pictures. Your pump will be the same basically. I have done it a few times and have a spare pump apart at the moment. Cleaning it will be a big job. Probably what has happened is the port where the fuel goes into the pressure head is blocked. I would check the pressure regulator valve first though the rings may havé rotted away leaving you with zéro pump pressure. Invest sèveral hours cleaning all the parts dont loose anythink ans peut together in a stérile place like à cleaning office desk. Sort iPad is self correction gin franchement gérer french ahhh!

    I have had an injector pump fail with a identical problem, dont pull it to bits just yet. The problem is there is a vane pump inside the injector pump, the vanes get stuck with crap. You can flush out the pump by removing the return line banjo and and the inlet line, and use a petrol fuel injector pump to circulate a solvent through IP for around 20 minutes. I used metho about 3 years ago on a vehicle after it died and it is still going strong.

    Hi mate thats sounds promising but I have absolutely no idea how you did it , could you explain the procedure you used in more detail....im pretty mechanical but injector pumps are a bit of a mystery to me, feel free to assume your talking to a dummy , I wont take offence.

    Ok get some fuel line a bucket, 4 liters of metho, an in-tank pump from a fuel injected petrol car, some wires, hose clamps. Remove the "fuel in" line from your IP and use a bit of hose or fuel line to connect up to your in-tank pump to your IP. Hook on a couple of jumper wires to the in-tank pump so you can power it with a battery. Throw the pump in the bucket
    Next remove the return line banjo and look inside the bolt that holds it down. You will see that it has a tiny hole that is very restrictive, so you will have to find a way of connecting a hose to your IP and returning the other end to your bucket. You can just jam a hose in the hole or get another banjo and bolt from the inlet side of an IP pump.
    Fill up your bucket with metho or what ever you think will dissolve your WVO Gunk the best and fire up the pump, watch for leaks etc. Once you have let it run for a few minutes you can rinse an repeat if you want, But i always then flush the metho out with some bio, or diesel.

    You can then reassemble everything and bleed your pump. If the your IP vane pump is working you will get a flow of fuel coming out of the return line when the engine is cranked or running.

    Ive done this a number of times, on different vehicles and it has always worked for me
    good luck with it. let us know how you go.
