Edelbrock Divided Heat Insulator

MPN: 9266 Catalog #: 001132959 Category: Hardware Kits - Other Check Vehicle Fitment

Product Details

The Edelbrock Square-bore Heat Insulator Gasket #9266 is designed to prevent percolation on Edelbrock Performer Series Carburetors exposed to extreme under hood temperatures. This gasket features a divided center which will allow dual plane Performer and RPM manifolds to seal properly to the carburetor. Prior to installation, check air cleaner-to-hood clearance to ensure that additional height of heat insulator gasket will Not cause interference. Remove air cleaner and all attachments to the carburetor such as fuel line, throttle linkage, and vacuum lines. Be sure to note the position or tag each piece to facilitate re-installation. Remove the carburetor and set it aside, then remove the old base gasket and any additional plates, such as Edelbrock square-bore adapter #2732. Remove the short carb studs and install the longer studs. Install the #9266 heat insulator gasket directly against the manifold, then replace the carb and all other connections. Note that gasket #9266 is rigid enough to replace square-bore adapter plate #2732, if required.

Heat Insulator Gaskets are designed to help prevent fuel percolation in Performer Series and Thunder Series AVS carburetors exposed to extreme underhood temperatures. Use number 9265 with open plenum manifolds such as Torker II and Victors.
