I am thinking maybe we should take JimB's lead (shown below) and connect
the two tanks through the drain holes.
then take it one step further,
only use one pickup
only use one sender
remove the selector switch and the valve
use only one electric pump.
Now we would have one large tank, (connected at the bottom and other places)
and have removed half of the trouble causing devices........

On fuel injected coaches, I toe a crossover between the drains of the tanks
to allow sharing of fuel right to the bottom which actually negates the need
for 2 senders. If the FI system dumps it's pressure into the fill rail, you
could draw one tank
totally dry without the lower crossover line.

Wayne,
I think you've confused Emery and me. I'm not his evil twin (that's Jim K);
but, I do have my fuel return line run into the Aux (fwd) tank drain. I
thought I had a picture posted of that installation but I can't find it
either on the photo site or my computer.
The significance of the photo is that it shows the skid plate I made to
protect the return line from road hazards. Briefly, it's a 1/8" steel
channel about 2-1/2" wide, 3/4" deep and 10" long. With the "U" open
upward, it has a mounting ear welded on each side by which it's bolted
where it crosses beneath the crossmember in front of the Aux tank. Forward
of that the "U" is formed upward to above the bottom of the frame rails to
form a skid. Behind the crossmember, the "U" extends just to the rear of
the drain plug so that it protects the elbow which screws into the drain and
accepts the return line. The width of the "U" allows room for a rubber
lined steel clamp on the line.
Is it strong enough to protect the line from a big obstruction? I dunno,
but it makes me feel better knowing it's there. I'm no more worried about
than the two electric fuel pumps which are mounted in the same area.
