First off i can only find the primer lines in the IPC and not the nozzle.
Second is the single primer nozzle into one side of the intake manifold adequate?
I was thinking of installing a multi point primer system or maybe just a few nozzles into the cylinders.

I did some more research and found the nozze AN4022-1 for 24$. I do not think i will be installing a multi point primer considering the manifold from Cessna is $1200.00 !

When I had a stock engine in my airplane I found that starting in cold weather was iffy at best, and, when the engine started to fire, it was ragged as hell during the time the primer was required in order to keep it going.
My solution was a trip to the salvage yard for a six point flow divider manifold off of a C-182 engine and nozzels enough for one in each cylinder. The toughest part was removing some of the 1/8th in. pipe plugs in the cylinders at the intake ports.
The installation of this priming system completely eliminated all cold starting and rough starting problems.
I bought the primer tubing and all the necessary fittings from Wicks Aircraft Supply. Very reasonable prices. Be sure that you understand that primer lines do NOT use standard flare fittings.

For your information, My wicks catalog, dated 2003, lists the AN4022-1 fitting at $5.93. I paid about $10.00 in the salvage yard for the primer manifold.
