ACDelco 12646996 GM Original Equipment Fuel Pump Insulator

The ACDelco 12646996 is a GM Original Equipment fuel pump insulator designed to reduce heat transfer and noise from the fuel pump assembly. This insulator pad sits between the fuel pump and the fuel tank, providing thermal protection that helps prevent vapor lock and fuel pump damage from excessive heat exposure.

Key Features:

• GM Original Equipment part ensuring precise fit and OEM quality
• Heat-resistant material protects fuel pump from tank heat
• Reduces fuel pump noise and vibration transmission
• Helps maintain optimal fuel temperature and pump performance
• Direct replacement for worn or damaged original insulator

This insulator is a critical component for maintaining proper fuel system operation and extending fuel pump life in GM vehicles. Replace when servicing the fuel pump assembly or if heat-related fuel delivery issues occur.
