What drives the fuel pump on a Y Block?  Does the pump arm ride on the cam or is there a pushrod or something?  I can't picture it and none of my reference material is helping out, much.  

There is a fuel-pump eccentric that is attached in front of the camshaft gear. The mechanical-fuel-pump arm is inserted through the timing cover and goes under the eccentric. As the eccentric rotates, it applies pressure to the arm, pretty much the same way as the water hand pumps that you see in old movies. Sadly, "The pump don't work cause the vandals took the handle." Thank Bob Dylan for the quote. 

When inserting the pump arm, make sure it is going in at a downward angle so it goes under the eccentric. Additionally, I understand that it is easier to bolt up if the engine is at top dead center and the eccentric is it it's low point on the bottom.

I usually just stuck my finder in the hole and rotated the engine to get the eccentric where I wanted it.

That makes sense.  Thanks so much.  My only experience is on...well...another brand of V8.  

..and thanks for the quote... I appreciate Bob Dylan more than you can imagine.  My first concert was Bob Dylan 1997- as a freshman in college.  In all I saw him 12 times before my concert going days fell by the wayside.  

Really dumb fuel pump question...
