Just to get the names right.

Tank 1 -> front left -> main tank -> feeds both engines when selected
Tank 2 -> front right -> main tank -> feeds both engines when selected
Tank 3 -> rear left -> reserve tank -> feeds selected main tank when selected
Tank 4 -> rear right -> reserve tank -> feeds selected main tank when selected

Thats the way it should be afaik

Just to put in some more confusion:

There are eight fuel Pumps in a Bf110 C.

Two pumps per engine, which are engine-mounted and driven by the engine itself. These two pumps are operated by two units 'Brandhahn Armatur' which have three purposes: first to filter fuel from any polluntant, second they work as a deshydrator, third they operate as a fuel cock. These units are fuel-cock-wise operated by the two red-knobbed levers on the left of the pilot. The lever either closes both units (Brandhahn zu), opens unit one P1 (pump 1 can deliver fuel) unit 2 or both.
Brandhahnarmatur is 'A' in following picture

'B' is fuel line connector to engine driven fuel pump

So thats only 4 pumps, right!

The Bf110 has 4 fuel tanks, 2 in each wing. The forward tanks are maintanks which can feed the engines. The rear tanks are reserve tanks. To use the reserve tanks you have to use fuel out of the main tank first and then feed fuel to the main tank out of the reserve tank. (remember engines only can be fed from a main fuel tank!)
Even if one main tank is damaged both motors can be fed by one main tank. To this every fuel tank is equipped with one immersion fuel pump for transfer pumping purposes. The direction of transfer pumping is controlled by the two lever switch to the right of the pilot.
C4 and C7 switching logic should be:
°|°
°|° normal switching for use of main tanks, left engines fueled by left main tank and right engines out of right main tank.

°\°
°/° transfer from reserve tanks to left main tank

°/°
°/° transfer from reserve tanks to right main tank

°\°
°|° fueling both engines from left main tank, i.e. if right main tank is damaged

°/°
°|° fueling both engines from right main tank, i.e. if left main tank is damaged


Whether that is correctly simulated, we have to find out.

i am using key shortcuts to conrol fuel.
so i have set two keys, every is to toggle throug the fuel'cock' settings of one side.
#1 front, rear, both, none (left engine , or in single engines planes )
#2 front, rear, both, none (right engine)
These are the two left levers.

The right instrument panel, when i use my mousecursor, i get fuelcocknummbers like #3.
I dont think one needs them.

This game is good in simulation some things, but it does not simulate the reality 100% - i dont think it will ever, and i dont think too it cant - never expecting it !

Wow, thanks for that post ZG15_FALKE, now I understand the system.

Seems as though it's not properly modeled in game as the front switch has no neutral position.

So what's the consensus on this subject? Are the fuel tanks working properly and I just haven't figured out the right way to manage them, or are they modeled incorrectly?

I have done some tests. It apears that the fuel tanks are not working correctly.

Each Engine is using the fuel from its own main tank. I couldn't find a way to get fuel from the left main tank into the right engine.


°\°
°|° Normal situation. Both main tanks are used until empty.

°\°
°/° Left reserve tank pumping into left main tank (if not full)

°\°
°\° Right reserve tank pumping into left main (if not full)

°/°
°\° Bug: Right reserve pumping into left reserve

°/°
°/° Bug: Nothing happens (Left reserve pumping into itself?)

The right engine stops after the 350l are used up, no matter what. It is possible to fill up the left main tank, but it is not possible to get reserve-fuel into the right main tank. According to manuals I have seen, the red light from the reserve tanks should be switched on when the reserve tanks are empty.

If I remember this right, it was different befor the latest patch. I think the front switch was controling the usage of the main tanks.

This is exactly what I had concluded. Can't wait for the fix so we can get more than 45 minutes of fly-time in a 110.


Prior to the last patch both engines fed simultaneously off of whichever tank you had selected.
Not that it matters now but it used to work like this. (Obviously historically incorrect but much simpler)

°\°
°|° Both Engines feed from front left.

°/°
°|° Both Engines feed from front right.

°|°
°/° Both Engines feed from rear left.

°|°
°\° Both Engines feed from rear right.

Cool!

A picture, even ascii, is worth a 1000 words! Thanks FALKE
