Engine problem worse than expected

Engine problem
We really have been hit by some bad luck on this one. Despite going to our best of efforts to drain the bottom of Yarramundi's fuel tank in Rabaul before filling up with new fuel we have a serious fuel contamination problem which has led to some serious engine problems that are not easily fixed.
Something nasty happened in the tank after we left Rabaul and we got the diesel bio bug right through the engine fuel system creating numerous blockages. This was confirmed today as we pulled the system apart. As written previously we have been told by a mobile engineer a reaction occured with the new fuel when it went into our fuel tank which must have had a dirty layer on the bottom. Today we took out the fuel tank - not an easy job - and have sent it off with on of the Yacht Club members who is going to clean it for us. As we emptied it we could see lots of little spots of coffee colour bubbles on the bottom of every bucket of fuel we pulled out. I am not completely convinced that it is just a chemical reaction as the bubbles sink indicating that they contain water meaning we got some sort of leak somewhere along the way. Or Mobile sold us very dirty fuel out of the 44 gallon drums.
The fuel tank is now being cleaned for future use but the engine fuel system still needs major cleaning. Some parts such as the high pressure fuel pump and the injectors are so badly clogged or covered in stuff it seems we may need to replace them. Not expensive parts thankfully but not easily available here in PNG ......probably. The other issue is the ex-pats here at the Yacht club all strongly suggest I do all the work myself as the local mechanics have "light fingers". This will slow down the process as I struggle to work out what to do and make mistakes along the way.
Rod the salvage man has been a great help in identifying various issues and explaining the workings of a diesel engine as well as lending tools etc. Adam has also continued to be a great source of energy, ideas and simply someone to get things done. Unfortunately he flies back to Cairns tomorrow. We will head into the main town Kokobo together to pay for his tickets and will visit some work-shops to see what replacement parts I can get here in PNG. Some parts are better cleaned and repaired than replaced as the engine is somewhat old. If you know about engines you will know what I mean. So I am also considering taking those now faulty parts for repair to a) Lae where there is a German mechanic who can do it all - but Lea is one of the most dangerous places on the planet so flying there with a box of broken engine bits is not all that attractive, b) Cairns - further away but a chance to have a break from lawless PNG and I can stay with Adam, and c) catch the flight back to To kyo on Saturday and get things sorted there for the week. Summer Obon holidays may present a problem in finding a workshop to do it though. Decisions, decisions!
For now, I'll go to Kokobo with Adam tomorrow and we will see what parts and workmanship we can find here locally and hopefully I won't have to fly anywhere.
Nothing else to report expect after a full day of hard work in hot weather working in disel fumes we are very tired. Adam fell asleep as soon as we got back to the boat from dinner and I am falling asleep writing this blog.
