I'm not 100% sure on this, because I have an early B, and an A - both of
which use the actual oil in that hose as their sending unit, but......the
way the flex hose works, the flare internal to the female threaded part
makes the seal - the threads do not make the seal, it is the flare.
Similar to AN fittings. The design with a sender (which I don't have) may
require those fittings to make a seal - which would be why you have the
flexhose. It may be replaceable with a solid line, but why?? The flex
line is universal to older motors (that ultimately go through a firewall,
and on a gauge), and it allows one the ability to put it in place easily,
since it's flexible.
