These are reproductions of three different voltage regulators from the late 1950s through the early 1960s. The decals are mounted so that the top of the writing faces the bottom of the mounting surface as the regulator is attached to the electrical panel. The voltage regulator information is not contained on the build sheets and the changes were probably made by Pininfarina to adjust the electrical system to the additional electrical equipment of the later cars. Voltage Regulator Decal 1R50A, Lusso #4391 and late GTEs
These numbers are used to denote the firing order sequence and are positioned in the top of the distributor caps. This package is for the numbers 1-6, for each distributor and a spare set in case of a mistake. Distributor Cap Numbers.
With the electric fuel pumps there is a fuel filter also made by F.I.S.P.A. The filter element is contained in a steel bowl which is painted gray or an industrial green color which has a decal telling the mechanic to be sure to change the filter. These filters are always packed with mud and rust on the old cars. Be sure that the tank is near empty before removing the filter bowl. Multicolored F.I.S.P.A. decal, used on cars near #1500
In 1959 Ferrari began production of the new 250 series “outside plug” engines. These engines had the spark plugs moved from the center of the engines to the lower side of the heads near the exhaust ports. At about the same time Magneti Marelli supplied a new series of red coils. These coils were in two configurations. The earlier version used a small tubular-shaped resister that resembled the American “Tootsie Roll” candy, hence the nickname “Tootsie Roll” coils. These were used as late as the early 250 GTEs. The can, bracket and the resister were painted red. The second series used a square-shaped ceramic resister. These coils were painted red along with the ceramic resisters. I believe that both the cans and the square resisters were painted the same color; however, over time the resister color might change a bit due to heat build-up. The coils with the square resisters had a separate mounting bracket with the bracket, pinch bolt and nut, and mounting screws plated with silver or white cadmium. The square resisters had the ohm rating silk-screened on the top surface. Both of these coils used a truncated oval Magneti Marelli foil sticker located 1/4″ from the bottom of the can on the “front” surface centered in line with the resister. The changes in pieces like these, which were supplied by outside vendors, normally did not coincide exactly with Ferrari model or yearly changes. The records of the timing of these changes are sketchy at best so teh restorers and judges are always looking for original components and photos to try to document the timing of the changes.
