If you stretch it to long, Hypotheically. Say you run the main tank dry and you have just a bit of fuel left in the aux tank (just about gone say running on fumes). Tehn you pit and refuel your main tank. Will there be enough pressure to push/pull fuel into the header and then to the carb, since your fuel outlet is lower than carb height, and you are strictly counting on exhaust pressure.
This is just one thing I noted in your comments and pics. When I had the Savage with the header tank, everyone everywhere said that the fuel outlet to the carb had to be above carb inlet heigth.
Don't take my comments the wrong way, in no way am I bashing, just trying to give soem thoughts and perspectives and hopefully solve a n issue before it comes one
The Pressure from the Main tank still pushes all the way to the carb. If the Aux tank is damn near dry and i refill the main tank, it still runs. The fuel is being pushed into the carb from the aux, from the main. The pressure remains the same wether full or low. I tried and tested this already. I even started with no fuel in the aux just in the main tank and fuel lines to simulate a situation like you stated. It kept going and refueled the aux tank at the same time. Aux tank position isnt as important ans a constant pressure in the lines. I placed the tank in many positions (Flat, sideways, left,right up, down, backwards, even hanging out the side.) I ended up with the same result. I found the lying flat position to work best for me cause it lowers the CG also... These are my resluts and findings, im not tryingt to rewrite a physics book, but it worked for me
