Okay I got an old Murray Riding Lawnmower (lawn tractor for the Southernese Impared) I'm trying to fix for my mom. The gas tank was cracked. So I had to take a hacksaw just to get it out. Yay for teh hacksaw Soooo... What can I use for a gas tank. I need something I can hook a fuel line up to and not worry about my mom driving it and it blowing up on her I'm thinking a closed system overflow tank for a radiator... Any suggestions welcomed PS: Happy Easter!!!
