It sits between the engine's accessory drive and the fuel pump, absorbing vibration and shock to protect the pump and maintain smooth operation. When this rubber spider becomes worn, cracked, or hardened, it can cause excessive noise, vibration, or timing issues, so it is often replaced during fuel pump removal or engine overhaul.
