Clamps
There are three types of clamps originally used on the 330 GT. These are Cheney, copiglia and Corbin clamps.
The copiglia clamps are used on the heater hoses, radiator overflow, cowl drain hoses, heater and defrost hoses, etc. They come in 2 widths, 5mm and 9mm.

| Cowl drain, by brake support | Air duct hose from blower to heater box |
 |
 |
| Manual heater valves† | Cowl drain, by fuse box |
 |
 |
| Radiator overflow hose† | Radiator overflow hose at overflow tank† |
 |
|
| Defroster hose under dash | |
Corbin (spring wire) clamps are used for small hoses where there is no pressure. Their main purpose is to prevent the hose from slipping off rather than a tight seal.
 |
 |
| Both ends of brake reservoir hose | Crankcase vent hose† |
Cheney clamps are similar to the normal hose clamps you would buy at any auto supply store. The main difference is that the band is not slotted for the screw threads. Instead, the band has indentations for the threads. These are common on English cars of the same era, so a source might be a Jaguar garage's old parts box.

| Oil filler and breather hose‡ | Fuel filler hose† |
 |
 |
| Upper radiator hose† | Brake booster hose at carburetor |
Here are the locations and types of the various clamps, as derived from the Ferrari and Pininfarina parts books.
