OK, I saw this film one time only on TV when I maybe 13 or so, so quite a while back, and have never run across it again.
Made in the mid-50s, maybe; bears a superficial resemblance to the The Wages of Fear, but made in the USA. Definitely not Sorcerer, William Freidkin’s remake of TWoF. Concerns a group of rough, tough truckers who are transporting some kind of volatile, corrosive rocket fuel in tankers over dangerous mountain roads. I recall one scene where some of the cargo leaks out of a valve on the truck and burns a guy’s arm. Unfortunately, I remember little else, including the title and/or names of any of the actors. Anyone have any idea what film this is?
