Hi Steve,
My what the diagram shows is what I got. The benifit of putting the the flow sensor in the return line:
- it still shows the health of the whole system not just the front end
- it allows calculation of how much fuel is being transferred when using the alternate tank
Even if in the front end, it still could not be used for fuel usage calculations. However, that is easlly accomplished by the use of an electronic totalizer like in the EM2 or Ed Andersons unit. (much more accurate too).
