No, sorry, let me clarify.

The leak I saw was NOT due to the firewall fitting.  That fitting on the
pressurized fuel supply line from the fuel pump was long ago replaced
with a metal fitting:

GoWesty suggests replacing that plastic fitting with a grommet instead
of a metal fitting.  I don't know which is better.  Here's where they
mention it:

Rather, the leak I noted was on the return line, just forward of the
firewall grommet, where it joins the plastic line.  Here I have bent the
rubber line to show the joint that was leaking, which is normally hidden
from view:

Both of those lines join the original plastic lines that run forward to
the fuel pump and the fuel tank.  It's those plastic lines I'm thinking
of removing, so the rubber hoses will be continuous from the fuel pump
to the firewall fitting (supply side) and from the fuel pressure
regulator to the fuel tank (return side).

GoWesty has a "Hard Plastic Fuel Line Replacement Kit":

But that page is confusing.  I believe it includes more hard plastic
line, together with barbed fittings to make the joint more secure.  Why
not run one continuous line, as I'm suggesting?
