You cannot make Sulfuros Acid from Zetta Industries cause Flint and Steel is disabled and so you cant get the 150 000 000 RF/block bonus. Please add a trading station by spawn for 1 Block of Sulfur = 8 Buckets of Sulfuros Acid or make another way to get Sulforus Acid fe: make it craftable with 8 water cells/buckets and the sulfur block in the middle.
you can, put the flint and steel in a dispenser or one of those vanilla blocks above the water then flick the lever to make your water into sulfur
