I think the sending unit has a gasket (flat AFAIK) and it may have
disintegrated or stiffened and broke after many years. This may be all you need
to replace. I wouldn't worry about finding a exact replacement, just a soft,
diesel fuel resistant flat rubber-like sheet of ~ 1/16" can be used.
Cut hole in it for sender arm and after assuring that the holes are lined up
between the unit and tank top, drive the screws through the 'gasket' and you
have a well sealed unit at the tank.
C&C had an access port cut into the tank on my 36 XL (1995) about 6 inches in
diameter. This was sealed with a similar, floppy piece of rubber-like stuff
held between the access cover plate and the tank with ~ 6 sheet metal screws
with a random but fixed pattern that must be followed!
I can imagine a worker just putting the plate over the hole and using a hand
drill to put 6 holes around the circumference--not at any precise angular
separation--"...just put them about evenly around the edge and seal the thing
up..."--especially when the tank was new and had no fuel in it.
Probably the way I would do it--never mind putting the holes every 60
degrees!!---symmetry is way over-rated!. :>)

Subject: Stus-List Fuel Tank Sending unit
Hi,
I have a small leak emanating between the sending unit and the top of the fuel
tank on my 83 Landfall 38.
Space is especially tight on these LF's and I'm wondering if anyone has had the
"pleasure" of changing the sending unit or replacing the gasket (assuming there
is one) on the LF 38, and what's involved. I'm trying to find some pictures of
what the specific LF (likely original) sending unit looks like but no luck. If
you have any or suggestions on replacements it would much appreciated.
Space is quite tight and only about 5-6 inches of clearance from the cockpit
sole.
The boat is on the hard and I'd like to tackle this before launch.
Thanks a lot,
/John
