Sine won't die just yet.
Just to keep things straight, I=92m going to now always refer to the =
Diesel Filtering System as The Polishing System. It is the system I =
designed and installed and have written about. Those new to this thread =
can read the first accounts for details.
I devised and fabricated CaptnWil=92s Diesel Tank Bottom Sampling =
Contraption =96 my wife will never forgive me either. It is a rigid =
pipe, flexible tube affair connected to a Par hand pump. All of this =
fabrication was necessary because the Krogen-42 fuel tank is curved to =
the contour of the hull, and the fuel inlet is located so a pipe will =
not go straight to the bottom of the tank. I withdrew about three quarts =
of contents from each tank and transferred the samples to zip lock bags =
(actually the Hefty brand since the closure system is better) for =
observation. As an aside, the zip/Hefty lock bags allow for much better =
inspection than anything I have tried. If you turn the bag so one corner =
is down, it concentrates the sediments in that corner and gives =
excellent information because it is clear.
The fuel was not sparkling, but light would shine through it. It was =
better than the sample taken from the Racor filter bowl after the first =
cycle of The Polishing system.
Some solid debris came up in the first couple of strokes of the pump =
handle =96 then only fluid. The fluid was darker at the first stroke and =
got lighter with successive strokes. The samples were first collected in =
a one-gallon anti-freeze jug and later transferred to the zip/hefty =
bags. While the fuel was in the jugs, no water could be detected.
It should be noted that adding the clearer fuel to the sample did not =
clear up the sample. It stayed its initial color and that color was not =
diluted by adding clearer fuel. That same phenomenon has been observed =
with every sample taken.
About a teaspoon of water was observed in each of the two samples. There =
was no sharp line between the red diesel and clear water. The water had =
some black debris on top and its color gradually changed from red to =
pink to clear at the very bottom point.
Discussion
This sampling routine should have been initiated at the beginning to =
give us information about whether the Polishing System normal pumping =
schedule will do anything below the fuel pick up of the tank.
At this point, we can only speculate about how, if at all, the Polishing =
System has affected this part of the fuel tank. I had expected much more =
bad stuff in these samples than I found which is encouraging..
On the other hand, no samples from the Polishing System after the second =
cycle had any water in the sample which is discouraging to the hope that =
the Polishing System will help here.
A sample will be taken after each future scheduled pumping.
2.1 No modification of the system will be considered until sufficient =
scheduled pumping cycles have been completed (and sampling analyzed) to =
give us a true picture of what is going on.
2.2 If it turns out that the tank zone below the fuel pickup is never =
cleaned by the Polishing System, I=92ll think about designing a means of =
getting to that part of the tank.
