I'm about halfway through my build and figured I'd see if anyone has any tips or comments on my system as it is to date. I have no graphics and haven't had time to upload any pictures yet but I'll do my best to describe my system.
To begin with, I have a 100 gallon in-bed transfer tank which will store the bulk of my WVO. A hose will connect the transfer tank to a smaller 8 gallon tank beneath the bed (right next to the stock fuel tank) which is heated by engine coolant.
WVO from the small tank flows through braided -6 AN lines to a 10 micron pre-filter, a Raw Power pump, and a final 5 micron filter. From there it flows through a valve system which allows the oil to return to the small tank during purges or on to the engine.
Just prior to the engine the line splits and is directed to the rear ports on the heads using OEM banjo fittings. Check valves have been installed in all four ports to prevent mixing.
The system itself is controlled by an Arduino microprocessor. There are two switches in the cab, System On/Off and Purge Bypass On/Off, which control the overall operation.
In theory, the engine will start on diesel and warm up the WVO in the small tank. Upon reaching 160 degrees the WVO pump will turn on and circulate the oil in the lines for approximately 10 seconds. This allows the entire system to warm up as well as remove any air from the lines from filter changes. After the purge cycle, a solenoid will close preventing the oil from returning to the tank. Upon reaching 65 psi the diesel pump will shut off and the engine should begin running on WVO.
More or less the reverse for shutdown.
My biggest question mark for this project is in regards to plumbing into the coolant system. How have other people accomplished this feat? Are you re-directing the entire flow or just a portion?
