Today I finished the fuel system plumbing, so I decided to put some fuel in the
tank and do some testing.
I can't run the engine yet as I have not finished the engine installation
completely,
but of course I can run the fuel pumps and measure the flow and pressure.
The fuel flow system, setup as a "sensor 1 minus sensor 2" installation,
indicates
zero fuel consumption, which is correct of course, as the engine is not running.
However, if I connect the sensors individually, they indicate that 130
liters per hour is flowing, about the maximum these fuel flow sensors can
handle.
The fuel pressure is ok, according to the fuel pressure gauge I have installed.
With both pumps on (I have them in series) the flow increases to over 140 liters
per hour, and the pressure goes slightly over the red line as indicated on the
"fuel over airbox pressure" gauge. Do I have a problem here?
I still feel that the floscan sensors are used on the edge of their upper range,
but so far the pressure loss does not seem to be significant. Actually I have
a little too much pressure with both pumps running. The carbs don't spill any
fuel though, so I guess it is ok. Any comments on this?
