Mine wasn't at the body point but rather at the top where it comes out of
the engine and turns down towards the whole in the firewall. At first I
thought the car had a valve cover gasket let go since there was a lot of oil
on the manifold and side of the engine. We kept checking the area for
leakage but didn't see anything. We finally started the engine and saw it
spraying from the pin-hole. We put a temp patch around the hole by placing
a larger hose over it and tightened that down with clamps. We still had a
seepage but no more spray.
Since taking the line off the car I have contacted most of the major
suppliers of Mopar parts and have been told "GOOD LUCK" this line is unique
to the 57 DeSoto Firesweep S-27. Have contacted a local hydraulic shop and
if they can't get the fittings they are going to do Neil's fix.

Subject: Oil pressure line-FIX
Back when I belonged to the WPC Club, I wrote a mini-article about how I
simply-fixed a pinhole leak that developed in Horrie's oil-pressure
line,
that 'runs' to the dash-gauge, thru the firewall.
Before I mention the 'fix', I urge ALL of you, with cars having an oil
gauge, to go out to your cars, & check these rubber-lines, for
contact/rubbing abrasions, like where the lines contact the
throttle-linkage-bracket, on the firewall.
One memorable day, 15+ years ago, I returned home, from a local
cruze-around, to discover an apparent engine-fire occurring, 'from' all
the smoke that was , then, billowing from under the hood!!
Quickly raising the hood revealed an actual oil leak, that was
dripping/spraying onto the driver's side exhaust manifold.
What I dscovered was that the oil-gauge line, from, oh, March, 1957
until that day, had been lying against the subject "t-l-b" , until, from
very minor driving-vibrations, a crescent-gouge had been worn into that
line, until the pinhole failure eventually developed, with the
aforementioned
"excitement". Fortunately, I was 'home' when the line-failure (finally)
occurred!!
Like Dawson, I encountered great difficulty in locating a NOS or NORS
(after-market) oil pressure line, & my local "hydraulic" shop didn't
have the esoteric fitting, that conects to the gauge.
What to do??
Well, kind of like, for the stolen Civil War train, "The General", when
its Union Army liberators ran out of track , they just moved the track,
from the rear, to replace a destroyed-section, lying in front of the
train.
Well, that's not a perfect analogy, but I do try to use "what's at
hand", to effect repairs, when ever possible.
What I did, to fix the oil line leak, & to PREVENT any future leak, from
its wearing against the "t-l-b" was to have that hydraulic shop,
merely, install (brass) CONNECTION-
FITTINGS, to the area of the failure. The "c-f's"
now lie against the "t-l-b", preventing any further abrasions/wear onto
the oil line.
Subsequently, no problemos from/with the oil line---btw, the area of the
'failure' is virtually "invisible", due to its small-size, and its
location, with its hand-in-glove fitment, lying against
the "t-l-b"-----the line, itself "looks" fine, but be sure to run your
hand all-around its length, to check for wear-points!!
