Re: Is a phenolic spacer required for 35 Super 8 Fuel Pump?

Mal -

Sounds like you've got another case where factory-installed countermeasures for vapor lock have been naively discarded at some point in the past.

Be careful which parts book you're checking. The 35-41 edition only covers the models that evolved from the 120/Junior platform. The Super Eight continued to be built on the old Senior chassis until 1939.

While scans of several parts books for prewar models are missing from our archive, the 33-36 Super Eights are covered in the 1933-1936 Packard Eight Parts List. It shows (on p. 97) the same bushing (2 per car), gasket (2 per car), insulating washer (2 per car), and insulator (1 per car) used across all Eight and Super Eight models for the period covered

Meanwhile, the 35-41 book also shows (Gr. 9.201) bushings and insulating washers (2 per car) for all models, but with different P/Ns for two different applications; neither is the same as the 33-36 P/N. Then, it only shows an insulator for the 17th Series (1939) Super Eight, but with a completely different P/N. Though built on a new platform, the old 320 motor continued for the Su8 that one year. Perhaps the single gasket shown for other models/engines incorporated sufficient insulating properties.

Since they didn't simply hand out part numbers like candy, there could be some significant difference(s) in dimension or material between these bushing, insulator, and washer P/Ns - such that the newer numbers are not backwardly compatible.

Source your replacements carefully.

BTW, I also checked the 30-32 parts book (pp. 88-90), and it shows nothing WRT to any bushings, insulator, or insulating washers for the fuel pump.
