It's not mine and I know there is some info about "converting to propane" in Tech Tips. I've never seen a conversion on an 1950 pickup so I borrowed the pictures. Someone has it listed on East Oregon Craigslist. I see what looks like a regulator at the bottom of the firewall. What is the device above it with all the hoses?
