it's aluminum, richard... 3x 8-an ports, one of which has an anti-rollover check valve which i'll use for a vent line.

from my research it seems that methanol attacks/dissolves the aluminum oxide layer that forms on the surface of all exposed aluminum. i do not plan on running 100% meth... too expensive and dangerous and prone to adsorption of water anyway.
what i'm looking for is a injection fluid that is cheap and easy to source anywhere. i'll probably settle on washer fluid, though experimentation will inevitably occur!
i've also tossed around isopropyl as a possibility, especially since no one seems to be using it.
