Methanol does attack aluminium, I just used the 25ltr plastic container the Methanol came in. I stuck it in the boot, put a hole in the lid and pushed a hose to the bottom. Then I put a few more small holes in the lid to prevent a vacuum forming and off I went. My pump is as low on the car as possible, so even the bottom of the boot is much higher, consequently it flows through very well and I only have to top it up every three weeks now.
