Only if you want/need full fuel. I seldom empty wing tanks; but when
I do I just fill wing
tanks and let the fuel pump refill the header tank.

Gary,
Not sure you are aware, but if you are running the wing tanks dry,
and using some from the main, when you fill up you need to fill the
main tank, let the fuel flow back to the wings thru the overflow.
(when the main cork quits going down)

Maybe the line itself is the restrictor.
In any event, the tanks slowly level out when being filled.
Like I said, what do I know.

Thats the first I have heard of a restrictor in the line between
the tanks????

tanks. I have heard that up to the brim, and I will lose fuel to
siphoning. I never had this problem in my 172, and I wonder why the
coupe tends to lose fuel this way. I am now putting too little fuel
in, and just want to know a good ballpark average the rest of you
men/women use. Thanks for reading this.
