Thanks. I can't say that a duel tank set up is my idea at all but I didn't research it much other than to note you don't want to have open flow from both at the same time. They are made out of 4" steel pipe that a buddy welded ends, the caps and a nipple on the bottom. I would have preferred the the older style bungs for the top but he said the only ones he would weld for me were the modern ones. He didn't want me "blowing myself up". His welder. His rules. (and I don't know how to weld). Each holds about a 1/2 gallon, feeds to a sediment bowl, then the central copper line to the carb. I can go for roughly 135 miles between fuel ups. They're held on with Stainless straps. 2 per tank and 2 on the frame with 1" heavy gauge chain links. They're rock solid.
