- I was a "Liquid Fuels Systems Maintenance Specialist" while I was in the Air
- Force. We worked mostly with JP4 jet fuel which is essentially kerosene.
- Diesel fuel is also essentially kerosene with lubricants and other additives.
- JP4 is susceptable to a form of bacteria that can live quite well and grow
- like mad with no light at all. It is a clear or milky sludge which usually
- grows best in storage tanks and then moves on to clog any filter residing
- downstream. This is a serious problem in the aviation industry since a
- filter which suddenly and completely clogs can cause the pilot and crew some
- some serious headaches. Fuel additives are now used to prevent the growth
- of this "bacteria".
-
- I have experienced this problem with a diesel tractor which suddenly stopped
- in the middel of the field one day while mowing. All three filters were
- clogged with a black goo. This resembled the bacteria I have seen in JP4
- except for the color. I suspect they are very closely related and wether
- it is plant or animal I won't argue over, but it is a living and growing
- organisim. I found that a thorough cleaning, and using a good diesel fuel
- additive solved the problem. These additives are readily available at any
- K-Mart and are designed to keep the fuel system clean and prevent the
- fuel from turning to a gel at very low temperatures.
-
- If you'd like to know more, drop me a line and I'll explain this "bacteria"
- business in a littel more detail.
