I was just having a look at this. The docs in the Community version report this:
But the config has this:
Tank.1=Name:TANK_REAR_LEFT#Title:Rear Left Tank#Capacity:121.9#UnusableCapacity:4#Priority:0#Position:-11.59,-7.0,0.9
Tank.2=Name:TANK_REAR_RIGHT#Title:Rear Right Tank#Capacity:121.9#UnusableCapacity:8#Priority:0#Position:-11.59,7.0,0.9
Tank.3=Name:TANK_FRONT_LEFT#Title:Front Left Tank#Capacity:41.6#UnusableCapacity:1#Priority:1#Position:-9.18,-7.0,-0.9
Tank.4=Name:TANK_FRONT_RIGHT#Title:Front Right Tank#Capacity:48.4#UnusableCapacity:0#Priority:1#Position:-9.18,7.0,-0.9
; COLLECTOR TANK
Tank.5=Name:TANK_COLLECTOR#Title:Collector Tank#Capacity:6.8#UnusableCapacity:0#Priority:2#Position:-9.18,-7.0,-0.9
They do have the Collector tank correct though:
They also got the unsusable quantity wrong.
So surely this should read:
Tank.1=Name:TANK_REAR_LEFT#Title:Rear Left Tank#Capacity:37.5#UnusableCapacity:0#Priority:0#Position:-11.59,-7.0,0.9
Tank.2=Name:TANK_REAR_RIGHT#Title:Rear Right Tank#Capacity:37.5#UnusableCapacity:0#Priority:0#Position:-11.59,7.0,0.9
Tank.3=Name:TANK_FRONT_LEFT#Title:Front Left Tank#Capacity:75#UnusableCapacity:3#Priority:1#Position:-9.18,-7.0,-0.9
Tank.4=Name:TANK_FRONT_RIGHT#Title:Front Right Tank#Capacity:77#UnusableCapacity:3#Priority:1#Position:-9.18,7.0,-0.9
; COLLECTOR TANK
Tank.5=Name:TANK_COLLECTOR#Title:Collector Tank#Capacity:6.8#UnusableCapacity:0#Priority:2#Position:-9.18,-7.0,-0.9
With that config in place it now looks like this:
Just tested reserve fuel as well, as that appears to work. With three gallons left, it switched to the Collector tank only, which is now dropping:
There was this weird limbo state for about 10 seconds where no fuel was being drawn from anywhere but the engine continued to run. Then the Collector started draining.
As expected, this was the end result, but for some reason it took about ~38 seconds for the engine to quit:
Does the sim model fuel in fuel lines as well? Or perhaps another bug.
Well, apparently it does. If not defined in the config, and they aren’t, each fuel line has 0.24 gallons in it. So for the collector that would be these two:
; COLLECTOR => AUX PUMP
Line.5=Name:L_AUX_PUMP_IN#Title:CollectorToAuxPump#Source:TANK_COLLECTOR#Destination:P_AUX
; COLLECTOR => FUEL COCK
Line.6=Name:L_AUX_PUMP_OUT#Title:AuxPumpToFuelCock#Source:P_AUX#Destination:V_FUELCOCK
So there was at least an additional 0.24 gallons of fuel to burn, which might explain those ~38 seconds where the engine kept running.
