The Fluid Burning Burners, Fluid Burning Heat Source and Fuel Burning Generator are available prior Fluid Handling is researched; It would make sense to make those items available after the Fluid Handling tech is researched.
Hope this idea helps :)

If anything, I'd make fluid handling available earlier, but, it's part of the challenge!
(Also it assumes you have other bob's mods installed)

For example, default settings, to make steel, you need to research chemical processing, to unlock the chemical furnace, because now it needs Oxygen.
This tech actually unlocks a small inline storage tank.
To get Oxygen, you need to perform Electrolysis, and get Hydrogen at the same time as oxygen... Hydrogen can be used as a fuel.
Most people solve the problem to make steel by piping the Hydrogen into a fluid-burning boiler, and the Oxygen into steel production.
