Can you automatically direct ISRU converter output?

[jkool702]

Is it possible to direct the resources produced by an ISRU converter into a specific fuel tank or a certain set of fuel tanks (rather than having it be equally spread between all fuel tanks)?

I have a ship with an ISRU converter. It has a lander with Lf+Ox tanks, but my main ship is nuclear powered and has liquid only tanks, so being able to direct the ISRU output to only the lander tanks or only the liquid tanks for the nuclear engine would save a lot of time manually transferring fuel (also trying to manually balance Lf and Ox is kind of a nightmare).

I would prefer a way to do this on stock but would be interested in any mods that can do this (TAC fuel balancer maybe?)

Thanks!

Try disabling the tanks you don't want it to fill. Right-click the tank, so it shows the fill bar, then click the little green arrow on the right, turning it to a red blocked symbol.

yeah Jarin's suggestion is right. Lock the oxidizer on the tanks for the nuclear engine from the tanks' context menus. You can do that once in flight, and you can also set that up in the VAB so if you're launching it again you won't have to set it each time you launch.

Also, run liquid and oxidizer conversion separately (don't use the Lf+Ox option on the converter, use the two separate ones instead). That way if one fuel type fills up first, it won't stop producing the other.
