Two new Fuel Injection Units (Part Numbers 7017355 and 7017360) are being used optionally in Production on 1962 Corvette 327 cu. in. V-8 engines of 360 hp. These Fuel Injection Units differ from previous models primarily in the design of the cold enrichment system. On the 1962 units a newly designed cold enrichment and diffuser cone assembly incorporates an almost conventional blade type choke valve, which eliminates the complex valving of cold enrichment systems found on past models. The electrically heated thermostatic coil, mounted on the air meter inlet, now positions this choke valve to provide necessary venturi signal "boost" for fuel enrichment.
Fuel meter design is unchanged except for redesign of the metering valve, use of a poppet type valve in place of the spill plunger, and relocation of the cranking signal valve to the covers of the power enrichment diaphragm. With the newly designed cold enrichment housing, vacuum for power enrichment is now drawn directly from the injector intake manifold. The new location of the cracking signal valve virtually eliminates the possibility of its failure due to back-fire.
The only difference between the 7017355 and the 7017360 fuel injection units is that a replaceable element fuel filter is used on the 7017355, while the 701360 unit uses a throw-away cannister type fuel filter.
