One of these holes(I think the top one) is drilled into the crankcase directly in line with the fuel pump push rod. Some people pull that bolt out and stick a longer one in there to hold the push rod up while changing the fuel pump. I've run across a couple leaking there before. It would only leak when you drove it, not just sitting there. Just a thought.

That was my problem. Didn't have a bolt there. No more leak.
