Need someone out there with a disassembled HPFP that is willing to do experiments.
I need a very simple test done --- and a video (as high res as possible) taken with photos. Take a drop (eye dropper sized) of fuel.
Put the drop (small at first) on the part that has the Diamond Like Carbon (DLC) coating on it.
If you have the new redesigned HPFP, put the drop on the mating roller surface as well. Try different size drops.
I want to see how the drop behaves --- surface tension.
Does the coating "repel" the diesel fuel?
Or does it "film" nicely.
----------------
Once this experiment is done, I would like to repeat the experiment with some common contaminants.
e.g. 5% water emulsion
Common diesel additives
Common unauthorized additives
Biodiesel B20, B100
Each time a new test is tried, the old part must be scrupulously cleaned with fresh diesel.
