How to... Prevent diesel bug | Motor Boat & Yachting 

We had a problem on our Bavaria 38 with diesel bug few years back and we installed a fuel polisher. Unfortunately the diesel bug problem was bigger than the fuel polished could handle so we had to internally clean the tanks. We were lucky to find a company in Australia that manufactures diesel tank inspection hatches (I think they are called Clean Diesel Australia or something like that). Once the tank was clean the fuel polisher kept it clean so far.

That was extremely educational. I didn't realise that diesel fuel could get that dirty. I recently discovered this educational series and am finding it so useful.

Prevention is the way to go: clean fuel equals less wear on engine systems and efficient operation.

I don't understand this. What's the difference between this and the standard primary and secondary fuel filters attached to the engine?

I throught fuel filters are put on the pressure side on the pump not the vacume.

Great vid, does the fuel polisher actually get rid of the diesel bug or does it just not let it through?!

Great video Joe, Where did you obtain the filtering device with the name Landau and what was the approximate cost? I have contaimination in a truck tank and want a permanent solution to keeping the fuel clean, since I have already damaged injectors after a fuel filter failure on the engine. Thanks in advance.

Why is the fuel red?
