I am using a Plano 4 drawer tackle box as my field box. I removed the drawers and have plenty of space now to add gear.

What I would like to do is add a tank inside the box for fuel.
I was looking at possibly using 2 dubro 50oz. tanks, which these are plane fuel tanks that usually go in planes.
The space available for the tanks is 9-3/8 x 4-1/2 x 8-1/2. The dubros will fit nicely and will hold almost a gallon of fuel.

Does anyone know of any issues that I might need to be concerned with using these types of tanks inside the box for fuel storage?

The dubro tanks have been the only thing I can find for this purpose so far. My hobby shop has some of the small red tanks but I think they are too big for my box.
Just wondering if anyone has any ideas for other containers for this purpose?

If so please ler me know where I can get them.

Thanks
