Fuel Supply is a feature found on pg 12 of Toolkit 2.
It is effectively the first bullet-point of the Machine metra-tait from B263.
Machines can still take Doesn't Breathe and it is unclear how Fuel Supply might affect Suffocation rules.
It still allows characters like machines to have advantages like Doesn't Eat or Drink or disadvantages like Increased Consumption.
The benefit is there is no loss of FP or HP from Starvation (cannot suffer damage or die from fuel lack)
- possibly not from Dehydration either
The drawback is that running out of fuel causes an immediate stop in function.
