Thanks to all who responded, I just ordered the pump, seal and locking ring. Now I have to go out right after this post to jack the truck up and drain the nearly 3/4 full tank of gas. It would have to happen right after I filled the tank. Oh well, just another adventure in owning a Hummer. I just replaced the ignition switch last week that had me stranded for two day's. Thanks again to everyone who replied.
