Well close enough, line can easily be protected and enough loop to
handle suspension travel, sure.

But you already have some fitting on one tank, presumably low down,
to get the fuel out - why not put a 'T' piece on that. On the other
side there is no need to have a fitting going straight down, it
can easily be put around the other side and be a 90deg fitting so
it doesnt face down etc...

Got a digital camera ?
