looks a lot more complicated than it really is. a brief description
oh and before I forget ya on the Fram filters, they generally suck however this particular one is perfect for this application, and one of the only fram products to rate worth there salt in most of the reviews I read. It can deal with the high pressure is high volume ( mostly due to it being mainly a rock strainer = crappy filter ) which is exactly what I wanted for the initial filters. So it kinda fit the bill, and it has a 20 lb pop valve to it can deal with the initial cold start up of the system ( assuming I can fit a heater onto it somewhere. I have space for one right smack in the middle. Speaking of which the heater would ideally go ahead of all the filters rather than behind which is where it would be if I put it in the water separator tank ( large tube to the right )
once the tank is filled ( using the same pump as it uses to filter with ) fuel is drawn up from the bottom left bung fitting through the pump head and over to the fluid pressure regulator just to the right of the orange filters ( Fram rock strainers ) there is a overpressure bypass that returns to the upper left bung fitting ( same side in the tank, there is a huge baffle which "almost" isolates one side of the tank from the other ) fuel then moves through the filter canisters at a regulated pressure and speed ( about 30 gallons an hour each filter, 2 filters to a set. Goes orange white and gold through the filters and then up to the centrifuge where it should be about 80 to 85 psi ( that part I'm not so sure about, will take a bit of experimentation to get it all balanced, I might end up filtering through the canisters first then upping the pressure and using the centrifuge on a second pass, depends on how much pressure the canisters can take.)
from the centrifuge fluid looses pressure and falls down a 1 1/2 perforated pipe inside the large cylinder just under the centrifuge. Water collects in the bottom of the cylinder and clean oil rises to the top and spills back into the right hand lower bung fitting completing the process, I hope. Worked in the back yard set up in 55 gallon drums soooo, hopefully it will work in the back of the truck. Should end up being a completely self contained fuel processing system. Now to paint the truck and get my ass a new seat.
glad you liked the tank
cheers
