fuel filler neck

[pamoffa]

I would like to change my rotted fuel filler neck and noticed the ones you can buy seem different, I dont see a hose clamp on the new ones and the rubber hose is already attached to the new one my concern is with the new one I will need to go through the trouble of replacing the hose also. has anyone installed one of these and had to use the new rubber hose. this is what it looks like hope the link works. http://www.autopartswarehouse.com/sk.../RB577095.html
