If "you can't trust it to within a quarter tank", you should probably
get it fixed.

Yeah, I know, it is common and nobody seems to care, but that isn't
what the regs say.

The regs are kind of vague about how precise and accurate the
indication has to be, so there's some leeway. But a gauge that's flat-
out broken is obviously beyond the pale.
