Hello, would it be possible for You to make a mod similar in functionality to Linked chests but for fluids?

no, Linked Chests only uses a vanilla prototype, which is an inventory linked to multiple chest entities; there is no existing prototype for linked fluids that work in the same way.

Personally I recommend setting up barreling plants on both sides of a chest, it makes it more complex than just a teleporter pipe lol

Yeah, this is what I made right now, but tought of simplyfying it with connected tanks. Thank you for swift reply :)

Just the thought, but: what if You created a chest with a fluid connection that converts fluid You pump into it in to item type and then converts back to fluid type if you pump out of it? Like 1k Oil fluid -> 1k Oil item -> 1k Oil fluid. Capacity could be configured by chest slots * stack size.
