I really like mine a lot. You might like to put a drop of nail polish behind your barrel shroud screws encase they back out like mine did better safe than sorry.
Sorry to OT in your thread GungaDin. Here it is N11H0423S she said it was made Nov.1,2011 she said the new part started with the Jan. 2012 production run. But I'm pretty sure the leverage exerted by the pump arm hitting the front screw's would even pop the new one the mount tab's are not that big that's why I suggest locking them down. Hope this helps some.
