I've got a auxillary fuel tank in the bed of my truck... Eventual plan is to convert it to hold SVO/WVO, but for the time being I want to use it, along with my regular tank for BioDiesel. Problem is the fuel lines to the tank are standard rubber lines. I'm thinking that I need to replace these lines with something else... My local A/P stores only carry rubber, any suggestions on what to use, and where to get it from?
