This time I know where it is, and what it is that's leaking.  Need help
either finding the entire OEM assembly, OR, what I need to get to make some
fascsimile of it.

Again, 88 Fox Wagon GL, 1.8L CIS-E.
The culprit is the hose assembly that goes from the fuel filter to the steel
line under the car that goes forward towards then engine.  The fitting that
goes to the fuel filter is male threaded.  The hose is unusually large in
diameter compared to the rest of the fuel hoses in the car.  Uses clamps
similar seen on air conditioning and hydraulic hoses.  Believe the other end
is similar.  Performancemarket.com sent me to ebay motors.  No luck.  Guy at
performancemarket.com didn't have enough info to help me order parts to make
some facsimile, neither do I.

Car is parked due to excessive fuel spillage from crack in the hose.
Appreciate any pointers.

I bought this kit for my Porsche 944, when I had an issue that sounds
similar to yours (not knowing exactly what a Fox's fuel line looks like.)

I would see if you could put something similar together.  Once you get
the hard to find metric adapters, any issues from then on can probably
be solved by simply replacing the (far more durable than any stock
product) Aeroquip AN-6 hose.

All the fuel lines under the hood transition from the steel line to
stainless braided lines similar to weblink.

The area where am speaking is under the RH rear of the car.  There are 5 or
so standard "rubber" fuel lines using standard hose clamps.  2 clear nylon
units that transition fuelpump/accumulator, and accumulator/fuel filter that
bolt on using a bolt with holes it to allow fuel flow.  The damaged fuel
line goes from the fuel filter to a transition setup that feeds the steel
line that goes forward to the engine compartment.  This damaged fuel line
has a metal male threaded fitting on each end.  Uses a seamless press-on
metal clamp, similar in AC and hydraulic lines, to hold these in place.  The
hose is externally larger in diameter than all the other hoses in the area
I'm speaking of.

Guessing that I'm going to have to remove the defective hose to ID the
fitting size at the very least to reconstruct a facsimile.  Locals are
telling me to take it to a guy in town that does auto AC lines.  Sounds less
painful.

    I'd be inclined to remove the line from the car and take it to
a local hydraulic fittings/hose supplier.  They can re-use the metal
lines and fittings and replace the hose, using the factory-style
crimp.  Those kind of shops may not carry hose rated for gasoline.  If
that is the case, you could probably source the hose from a local car
parts store.  Make sure the hose is rated for at least 100 psi.  The
fuel pump produces around 50-80psi.

that could work if you have a place like that.  He probably can repair
it using your old fittings.  Make sure he uses "fuel injection" hose not
standard fuel line.
