A 1x1x1 fuel pump block that takes a small amount of fuel (<10mb/s) to enable pumping in compact spaces. Fuel could be delivered either from siphoning some of the fuel its pumping or a separate input on the side for pumping other fluids. A notable application of a turbopump of this style would be making rockets and missiles in reasonable form factors.

How would it then receive a rotational power to operate?
forest karma
It would burn fuel
Internally, as a combination of blocks for the sake of space efficiency

Okay, but wouldn't it mean extra setup with hoppers or something to provide a fuel to it?
Oh wait
I see what you mean
forest karma
Liquid fuel, like turpentine or tfmg gasoline

Like providing fuel from the side?
forest karma
Yes, from a pipe, or taking some from the line its pumping if its an acceptable fuel

Okay, my bad, didn't read the full message carefully before 😅
I actually like this idea, fits nice. Gotta ask others

Liquid fuel, like turpentine or tfmg gasoline
but do turbopumps need some initial push, like with compressed propellant/gas which gasoline is not
forest karma
perhaps it would always pump into a reservoir reserved for its own use, or on redstone signal

i would like the turbopump to be integrated into the engine
forest karma
i like that too, but i think there should be both
in case there are bizarre space constraints for specific designs

I suggested it and got called lazy :(
