The fuel unit consists of three cylinders: two outer fuel cylinders and a central cylinder. Each is about a foot long, and 6 inches in diameter. The cylinders can contain up to 23 liters of a mixture of gasoline, rice wine (sake), and tar. Pressure is controlled by two manually-operated needle valves. This tank assembly was fitted with straps to permit it to be carried on the operator's back like an infantry pack.<ref>[http://www.lonesentry.com/articles/japanese-flamethrower/index.html U.S. Intelligence Report]</ref> | The fuel unit consists of three cylinders: two outer fuel cylinders and a central cylinder.
