How do you prime fuel and oil systems?

After draining the fuel tank and replacing the Carborator...how do I prime the system?
Also...same thing after draining oil tank and lines?
 
When I did my fuel lines I ended up taking the return line off of the carb and blowing air into with my mouth. This will force gas from the tank to start moving through the hoses. You should hear the fuel tank make noise when you do this. One I got the gas to the carb you'll see it come out where your hose is supposed to be.

For the oil lines, I would suggest checking out the shop manual as it details it in there pretty well. Did you change the small lines as well as the larger lines? The basic setup is to open the bleeder valve on the oil pump until all the air is out of the lines going to the tank and so that you don't have any air bubbles in the oil filter. If you changed the smaller lines as well you need to add put a little oil down your spark plug holes and then hold the oil pump to its wide open position with your hand while running the ski. You will see the oil move through the lines. Make sure there are no bubbles in those lines. This is somewhat of an abridged version, you should be able to find some other info on here on it as well. If you took your carb off you'll also want to make sure that the oil injection cable is setup properly. There are 2 notches that need to align. Again, this is in the shop manual so it is probably the best place to look.
 
For the fuel, I use a hand vacuum pump from Harbor Freight to get it down to the carbs. This keeps you from cranking so much and also checks to make sure your system is vacuum tight since it actually sucks the fuel out of the tank. For the oil, there is a bleader screw on the side of the oil pump. Open it up until oil dribbles out. Then some add some oil into the cylinders then start it with the oil pump held wide open, and idle it slowly until the oil moves all the way up the lines to the motor.
 
:agree:
Here is a pic of the bleeder screw and where the notches are that have to be lines up.


 
I know most do not like putting extra use on the starter but for me, I open the oil bleed valve to get the oil down to it and air out and tighten the valve. I put my spark plugs on their grounding post lugs and while holding the oil lever open, I crank the engine for 10 second bursts until I can see the small tygon lines are totally full of oil.
