I found a replacement fuel tank for my 1997 GMC Yukon four door. It is out of a 1999 Chevy Tahoe. The lock ring out of the replacement tank is all rotted so I need a new one. The lock ring on the 97 Yukon is like one of those ninja star looking ones where the hooks are free on the outside of the ring. The lock ring on the 99 Tahoe is a circle with slots where the tank hooks go into. Does anyone know if these rings will fit either fuel pump? I'm trying to buy a new one and not sure if the full circle one will fit my 97 fuel pump. Thanks
