In creative mode I can click the fluid tank with a bucket of lava and it will fill the tank, but when I go to survival mode the lava gets placed as a block outside the tank. Any suggestions?

This issue has been marked as stale because it has been inactive for 3 weeks. It will be closed if it remains inactive for another 3 weeks.

This issue has been closed since it has been inactive for 3 weeks since it was marked as stale.

I think this might be intended in order to necessitate the item drainer in survival

I'm experiencing a similar issue with the Creative Fluid Tank.

When attempting to set the desired fluid to provide (e.g. the tank is empty), right clicking with a bucket simply places the fluid in world if the fluid is placeable (ex. lava).
A brief inspection of the source seems to indicate that the first fluid inserted sets the desired fluid and all others are voided
Alternatives attempted:

1. Pool of fluid in world with Hose Pulley extended into pool and Mechanical Pump connected to Pulley and Tank.
   Result: Fluid is voided when it reaches the Creative Fluid Tank.
2. Bucket of fluid right clicked on Item Drain, Mechanical Pump connected to drain and Tank.
   Result: Fluid is voided when it reaches the Creative Fluid Tank.
   (NOTE: Behavior of #1 and #2 was partially expected due to description on Creative Fluid Tank about fluids inserted being voided.)

So, my question is: How do I legitimately configure the Creative Fluid Tank while playing in Survival?
(NOTE: I did confirm I could configure the desired fluid in Creative Mode.)

Other (possibly unrelated) details:
I was playing the modpack "Create on a Potato" version 1.16.1 on Minecraft version 1.16.5 and the Creative Fluid Tank is a quest reward for completing the "Cooking" quest line. So, if the above behavior described above is intended, I'll let the modpack author know.

Thanks for the awesome mod!
