These SBC Phenolic fuel pump insulators are made to take the place of the steel plate that is between the fuel pump and the block on the SBC. The insulator will limit the transfer of heat from the block into the fuel pump, therefore keeping the fuel passing through it cooler.

This universal Phenolic fuel pump insulator works with all domestic V8’s except Ford Clevelands and Oldsmobiles. The Phenolic material will limit the transfer of heat from the block into the fuel pump, therefore keeping the fuel passing through it cooler. It installs easily between the fuel pump and the mounting boss on mechanical fuel pumps.
