fluid crafting pipe(s)/module(s)

item into fluid crafter
for example
thermal expansion magma crucible put x amount of redstonedust in and get x amount destabilized redstone

fluid into fluid crafter
for example
tinkers construct smeltery x amount of molten Aluminum in, and x amount of molten Copper and get x amount of molten Liquid Aluminum Brass

Sattelite pipes do your Trick ;)

yea but it is a pain in the ass to set that up

@Bitterholz nope, there are no fluid results. So crafting with fluids work, but crafting fluids does not.
There are workarounds though, because you always can craft an item in those two cases though.

@theZorro266 I did it before, I had a Buffertank and Produced new fluid on Usage wqich got routed into the Tank ;)
