275GTB/4: Fuel and Steering Shaft
The mechanical fuel pump had parts that needed plating. The top cap was
incorrectly plated gold cadmium, which needed white cad plating, along
with all the screws that held the whole unit together.
I removed the mismatched and old yellow fuel lines with the incorrect
collars so I could make new lines with correct feurlles and plated
ends, but noticed a strange split in the middle of one of the hoses. At
first I thought the hose had been cut or abraded through, but on closer
inspection, I found something I had not seen before.
The normal yellow sheathing on Ferrari hose is made of several layers
on materials, with an inner spiral wound wire, white string, a rubber
liner, yellow sheathing, and an outer spiral wound external wire.
Somehow, this hose had just the outer yellow jacket and external wound
wire, but inserted inside was simple autoparts store rubber fuel line!
Someone may have painstakingly managed to insert this black rubber hose
into the yellow sheathing to mimick the correct hose. The split I found
in the longest length of hose was possibly to feed the hose into the
sheathing from two pieces of yellow hose. I imagined the
longer the length, the harder it must have been to slide the inner hose
into the sheathing. This method explained the why the wrong cable ends
were used, because they were simply for looks! If my theory doesn't
sound right, could there be hose out there that was orignally
manufactured with regular rubber hose inside?
Correct yellow hose is not cheap, and someone may have gone through
great lengths to create a reasonable facimile, but I noticed something
wrong the first time I saw the line. I just couldn't put my finger on
it until further investigation. If I could spot a problem, I'm assuming
a judge would see the same thing. The next time you see the fuel lines,
there will be correct parts, finished correctly, and installed
More indescriminate black paint was found on parts of the steering
shaft. The usual detailing notes I use for this area is as follows:
steering shaft: Semi-gloss black with paint going all the way down to
the end before the u-joint.
u-joint: natural steel (removed in this picture) or paint See discussion below
bolts securing u-joint: black oxide
safety wire securing u-joint: black oxide finish
steering shaft yoke with female splines: black paint
castle nut and pinch bolt on steering yoke: black oxide with a cotter
pin (Ferrari style cotterpin treatment which I'll cover later along
with yellow paint daub)
steering shaft going into steering box: black paint
There are witness marks that line up the steering box, shaft and yoke
that should have the steering wheel lined up straight.
a Ferrari collector in Europe sent me this picture of a original
steering yoke with paint on it. He also thinks some ujoint sections are
bare steel because they were replacements. More data points!
All these little details sound anal, but is not that bad when you're
doing them right the first time. What's time consuming is undoing the
damage done by someone with a spray can trying to make everything
