Fuel Path:
Fass Draw Straw to FASS Pump (w/ higher flow spring) to Y connector in the video.
Through the heads.
The front of the block is my "return". Fed from the rear.
I need to put that video on youtube and do a proper right up.
The fuel exist the fronts into 90 degree to AN fittings (cant remember the part,but the other 6.0 truck guys know. Those two lines are the high dollar PITA PTFE, and run up to the aeromotive.
The aeromotive then uses the STOCK fuel (feed or return) and the other (return or feed) was deleted. The stock line ran back to the tank.
The aero motive is mounted to the stock fuel bowl, which has been deleted. (pretty trick)
If you are doing this in-situ, as in IN the vehicle, I recommend getting a second set of fuel lines for the back.
Earls also has a tube/ferrule - to AN fitting that will allow you to cut the stock tubes (They are the only banjo I could find that fit the head)
