Thanks to all of the wonderful posters here, I am delighted to say that my car is back on the road after I replaced the fuel pump. I don't recommend doing this yourself if you are rich enough to pay someone else to do it.
I sourced the VDO fuel pump form the USA for 145USD plus shipping to Australia. The cheapest that I could buy it locally for was 540AUD
I really appreciate all of the tips, help and advice that I received here in this community. It made my job a lot easier. This job was very fiddly and complicated. The 22 year old plastic housing scared me. At over one thousand dollars new, I knew that I had to be careful and probably lucky too.
I have assembled a document detailing my 'adventure' and am posting it here. It may be good for a laugh!
