mod for fuel swapping?

[Somtaaw]

Wasn't really sure if this should go into mods, suggestions, or question forums so I'm just going to throw it here for now.

 

Is there a mod for fuel switching? I'm starting to design a new spaceplane that's going to be exclusively for space, and I want to make it ion-powered for a sort-of low-signature SR-71 meets EA-6B Prowler sort of plane. I'm still looking at exactly which plane parts I want to use, but with either mk1, or mk2 plane parts use either LF or LF+O, and even the smaller engine shells hold the same. So to make my plane exclusively ion, means I must use radially attached xenon tanks, and then figure out how to properly conceal them, without making it ungodly hard to refuel the spaceplane.

 

 

On a side note, wasn't there a fuel mod that allowed you to set relative fuel priorities? Something about fuel automatically 'flowing downhill', so you'd set fuel tankers relatively high, stations somewhere in the middle, and everything else low, so upon docking to a station you auto-refuelled? I can't remember the name for that, but it should help me with refuelling hidden xenon tanks.

Real Fuels lets you put any fuel in any tank, and it adds a bunch of real world fuels also. I've only used it as part of realism overhaul, so I don't know how it interacts with stock engines, but it's worth a shot. 

Not sure what mod does the automatic refueling, but TAC Fuel Balancer could at least make the process easier.

Add-on question moved to the add-on subforum.

@Somtaaw I sense a hiigaran,

For fuel switching KSPI will do some, the MK2 KSPI integration will attempt to add interstellar fuel switch to any LF/LFOX tanks that don't conflict with another mod.
Worst case scenario; if you really need the part with a specific fuel you can copy the part .cfg, change the name inside the file, and change the fuel type to whatever you need (or paste an interstellar fuel switch module if you have IF installed)

Real fuels will do if you plan on using stock parts, but if you have any parts that run off anything NOT LF/OX i do suggest Interstellar Fuels.

also, TAC fuel balance will only work with LF/OX/MP fuels. if you have 2 tanks full of liquid nitrogen not only will it not balance them, it won't calculate them for weight and hence will NOT balance your craft.

Since it's a plane, you could grab the github versions (not the release package) of B9 PWings and add Xenon to the fuel switching capabilities by adding a new node to this file (supporting more fuel types is the entire reason I'm adding this functionality after all...)
