The Story
This 32mm Motronic Injection Insulator Set (6 pieces) is used between the intake manifold and carburetor base on Weber IDF and PMO carburetor setups. These insulators act as a thermal barrier, limiting heat transfer into the carb body and helping maintain consistent fuel temperature under operating conditions.
On air-cooled Porsche engines running carb conversions or PMO systems, these insulators are a known wear item. Over time, the material hardens or degrades, reducing its ability to isolate heat. That often shows up as fuel percolation, inconsistent idle after heat soak, or hard hot starts. Replacing them during a carb rebuild or intake reseal is common, especially on engines that see regular street use or warmer climates.
PMO components are widely used in Porsche carburetor conversions for their consistent machining and reliable fitment across Weber-compatible setups.
Technical Details
- Manufacturer: PMO
- Part Number: (confirm if needed)
- Size: 32mm
- Quantity: 6 insulators
- Position: Intake manifold to carburetor base
- Application Range: Weber IDF and PMO carburetor systems
- Function: Reduces heat transfer to carburetor body
