Here's a run through of the water separation test. This is #2 diesel, with a cup of blue food dye added to it, at 0 minutes. All the dye (WATER) is settled at the bottom.
Then I gave it a really good shake!!
All the dye was in suspension
After 2 minutes, some settling is occuring
After 5 minutes, most of the dye has settled out
After 10 minutes, the majority has settled out
At 15 minutes it's all separated.
The way I'm going to do it is to pour 2 gallons of dyed fuel through each filter. I will pour 1 gallon in 2 minutes to make sure the 1/2 cup of dye ( water) is in suspension, then mix another gallon and the other 1/2 cup of dye and pour it in 2 minutes.
The collected fuel will sit for 15 minutes and I will suck up what water has collected in the bottom and measure it. I will also drain the filter and see whats collected in there.
I'm starting with 1 cup of dye in the 2 gallons of fuel.
In a perfect world, there should be ZERO water in the collected fuel, and cup of water in the fuel filter sump, which about is it's maximum capacity.
I'll let you guys know how it goes on Sunday.
