Mounted a 4 gallon cell on the package tray a long time ago. Before I knew that methanol eats aluminum. I used aluminum fuel line for the entire run from the trunk, to the engine bay and used Fuel hose from there to the uppipe. Been in my car for just about 10 years and only had one leak. I was using denatured prior to now... I switched to Meth and still no issues. Bought line to replace the aluminum if it ever ate thru when I switched to Meth but its been a few months so far and all seems well.
