Question for Larry,
You mentioned it is advisable to have shutoff valves for the wing tanks - do you have them on Mangy?
If you have them, where did you get them?

Yes I do have a valve at each wing tank. I sourced them through the aviation department at my local ACE hardware. Just a standard ball valve.
I plumbed my system with a short length of fuel injection hose from the tank to the valve, which is solid mounted to the airframe, then hard lines to the header tank. Then hard line from the header to the aux facet pump and on to the main shutoff on the firewall (remote operated ball valve). At that valve I have a bulkhead fitting through the firewall to fire-sleeved fuel injection hose on the engine side to a metal bodied filter just before of the mechanical fuel pump. From the mechanical pump to a pressure sensor and flow sensor and finally y-ed to the carbs, with no return.

I bought some ball valves off Amazon

I put them on the vertical that runs behind the pilot/passenger seats right above filters that I also bought from Amazon

I used yellow Tygon fuel line. There is a short piece between the bottom of the valve and the top of the filter so that I can disconnect the fuel line and attach a hose for draining the tanks at annual. The valves and filters are secured to the vertical with UV resistant zip ties that I'll change annually.

Larry,
Thanks for the detail on your system. I can see the merits of a ball valve as it eliminates any obstruction/resistance to flow compared to other types of valves.
