How to remove the strainer from a fuel pump?

[jkufen]

Can anyone tell me how to get the strainer off of the pump? I have messed with it a little bit and it doesn't seem to pull off or screw off and I didn't see a clamp of any kind. Any help? Also is that the only strainer in the system? I know there is the one fuel filter under the driver door and the strainer in the tank. Is there any more any where else? Thanks!
