Is it really necessary?

How have some of you done it?

I'm thinking that there are two major possibilities:

Tee from the fuel selector valve to the boost pump (non pressurized side) to a
Cessna type pump-knob to three of the four cylinders (fourth for MP?).

Solenoid from pressurized side to single line with three outlets for three of the
four cylinders (fourth for MP?).

Pictures, descriptions, parts lists would be appreciated.

NO! It is not necessary. Page 3-3 in the O-320 Operators Manual has the start procedure
for fuel injection.

Imho, primer is a liability on an injected engine, rather than any sort of 
benefit.  The nice thing about injected engines, at least the Lycomings I'm 
familiar with, is that you can prime the engine with the injection system. 
You already have a direct means of feeding fuel to the cylinders.  There is 
no need (imho) for a dedicated priming system on an injected Lycoming.  Just 
more stuff to buy & more stuff to break.

It never gets old, how quickly my engine (IO-360-A1B6 + Slick IC + Plasma 
II) fires up when cold.  Cold starting an injected engine, particularly with 
electronic ignition, don't blink, you might miss it!  ;-)
