What is this?
 

Anyone know what the short 90 degree pipe is coming out of the motor behind the fuel filter? Mine had about an inch of plastic hose still on it but that was all. I assume there should be a hose on it going to where?

That is for crankcase ventilation. A hose is attached to the elbow and drops down by the oil pan to allow excess crankcase pressure and gases to vent to atmosphere.
