fuel pump question

well thanks to this site and everyone here i tackled my project of rebuilding my fuel bowl and changing my fuel pump. all went well today in the removal process, i went and bought my new pump from napa 110.00 my only question is is that tappet suppose to be able to be pulled out? i ask only cause i'm a little unclear as to how the mech. part of this works, i understand the cam pushes the tappet causing the pump to work but.... i guess i don't fully understand..??
Thanks guys!

I don't think the tappet should be able to be pulled out of the pump. I have an old pump lying around here somewhere, I guess i could give it a yank.

Huh, guess you learn something new every day. What keeps it in there then?

Not sure other than luck but thats why they say watch when you pull the pump to make sure it doesn't fall in the engine

I knew that it was possible for the tappet to fall out and end up in the block (that's why you unbolt it then turn the engine over by hand until it lifts off the block) but I just though that was a symptom of a worn out pump. Good to know. Thanks for setting me straight Mike.
