CMP Ford F-AT Quad...help?

[DaveW]

I need some more help!!

But first, the current state of affairs:




Okay...

Fuel Tanks....I assume the Quad Gun Tractor has two tanks, both the same.
Are they the same size as the larger, longer vehicles?

What are the rough dimensions of the tanks?
Mine are scale 10" x 10" by 31" long...which I think is too small.
I'm also not sure if they are close to square, or are they rectangular?
(wider than tall?)

And, what is the position of the filler neck.
I've got pics of Tanks with filler necks in different places...I don't know what tanks go with what vehicle.

Exhaust system...
my current plan is to create a y-pipe under the motor, connecting to the left side pipe.
Then straight back to a straight inline Silencer, with a 90 degree outlet pipe after that.
The Silencer appears to mount under the frame inside of the left fuel tank.
But I am unsure of where the exhaust outlet sits.

Can anyone answer any of this?
I appreciate it if you can.
