My advice is go install a system that is suggested by ZAC or has been use on a certified airplane. The primer system I installed on my O-360 in my 801 was modeled after the one in a Cherokee Turbo-Arrow. I came off the pressure side of the fuel block to a solenoid (from Spruce) to all 4 cylinders. I just turn on the fuel pump then push to open the solenoid for 3-7 seconds depending on the temp. It normally starts right off.
I have 800+ hrs in a PA-22 that used vented fuel tank caps. They work just fine. I had more water in the gas from fueling during a rain than from the caps. I have 230 hrs on my vented caps in my 801 and have not had an issue with the caps.
I'm really excited about my new bigger tail with VGs on 3" centers. I can shoot stabilized approaches at 40 MPH indicated which is 45 MPH GPS. Talk about short landings!

Just finished flying off my 5 hrs on the new tail.
Starting to install full lotus floats.
I am still working on FWF on my 801 with a Lycoming O-360. I do not
have any experience with the Lycoming, so I am looking for input on the
primer system. Do I need it? If I need it, what parts do I need? How
is it plumbed in? The engine I have has the lines installed for the
system to cylinders 1, 2, and 3. It has a fitting on cylinder #4. See
pictures below.
And while we are on the fuel system, I want to know a little more about
the vented fuel caps. The fuel caps I recieved are vented and the
construction manual mentions: " (Note: Vent tube for the wing tank is
required on the bottom of the wing if the fuels caps are not vented).
Therefore I did not put vent tubes in my wings. Now after reading the
list yesterday, I wonder if I made a huge mistake by omitting them? I
looked at Gary Limings website and see that he made a different cap for
his tanks: http://www.liming.org/ch801/fuel.html Do I need to do the
same thing or will my vented caps work ok???
