My apologies if this has been covered before.

If you can position the cell within 12" of the original tank, there is no maximum size?

If you have a car like a BMW the ITCS states "trunk mounted fuel cell no larger than stock"

Now then: If you can make it fit in your BMW, can you mount a fuel cell in stock location? If yes, can it be any size?

If you can't. It seems that every car except BMW can run any size fuel cell, BMW can only run a stock size fuel cell.

Is this another case of THE MAN keeping BMW down?

Enquiring minds need to know
