Pump install is pretty easy...  if you have all the parts.  You can do it with basic skills.  Nothing tricky.

I am going to study this Clymer manual and do it myself. I have to figure out how the system works. It seems the pump must have a line going to the carburetor. It is not connected now and is on pre-mix. I have get a complete understanding of how it works and the only way to do it is dive in and work on it. Haha.

There will be a thicker pipe going from the two stroke oil tank to the pump, and a thinner pipe going from the pump to a nipple on the carb.

Partzilla and CMSNL are both good for online parts manuals (CMSNL also has a fair few photos).
