Aha! Sounds like you've fallen for the trap of believing the fuel guages. Both main and subtank guages not only go way beyond zero, but are hopelessly non-linear. The bottom line is to empty the tanks completely to accurately find out their capacity. You need to do a couple of checks:
- Try filling the sub-
tank after you've let the pump empty it, and you'll probably get your 30L in. And note the fuel guage setting when empty - will most likely be way below zero. Also note how many litres to fill back to the zero setting and the halfway setting on the guage.
- Similarly, with fuel in the subtank, try seeing how far you get on the main
tank. Again, note a few things; The distance when the light comes on, the distance when the guage reads zero and the distance travelled to empty after the guage reads zero. Only transfer as much fuel as you need to the main
tank to get you to a filling station so you can check how much fuel that main
tank takes. And when filling, note how much fuel to fill back to zero and half way.
You'll get some interesting results and should note these for future reference.
