Fuel Tanks emptying mysteriously

[Fabus1184]

In my build i have like 40 fuel tanks, but the second i spawn it they all get empty in just a few seconds, i have double and triple checked everything for leaks, rebuilt the entire fuel system and i dont know how to fix this, sometimes my build also spawns with exactly 0 fuel in all tanks, but this can be fixed by moving around some piping,
pls help!!!

Every fluid component has internal buffers which will fill up first before putting it into the next connected component.
This already leads to misconceptions with the condenser.
Having multiple fluid tanks directly connected with each other can lead to the player thinking the tanks empty on their own, while it's just the buffers filling up, leading to some of the tanks getting empty. One buffer can hold up to 10l, with 40 tanks you'd have 80 input+output buffers soaking up to 800l.
The fuel isn't gone, it's just sitting in the buffers.
The main problem with this is that it's very hard to tell the remaining fuel/runtime due to the buffers.

Use custom tanks instead, if you use dummy microcontrollers for the walls you'll also end up with more volume and due to a more reasonable input/output amount you'll get a more accurate fuel level and consumption reading.

No, they're really emptieing, I installed a seperate dial for every fuel tank, and the second I spawn my vehicle, if there's any fuel at all, all tanks are emptieing until everything is at 0.0, if I start the engines while theres still some fuel left they can run like 20 seconds before all fuel is gone and they turn off. And I should have plenty of fuel, I installed exactly 44 tanks so that should equal just over 8000l of fuel, and I dont have 800 pipes connected xD

Prefab tanks can be buggy at times. It might be just a matter of having too many tanks and the computer not being able to do the calculations to keep them all full. If you need that much fuel, a custom tank or 2 is a much better option. If you need 8000L you can build one custom tank that is 14x14x4 blocks and get 8250L capacity. 4x4x4 is 1000L. So unless you need to spread those prefab tanjks out for some reason, a custom tank is a much better option. Even 2 or 4 small custom tanks are better thab 44 prefab tanks just because of how many issues prefab tanks can have.

if you tick "auto refuel" off in custom mode.
you may get a bug with no fuel in the tanks. hope they will fix that soon.

yeah I experienced that too but the described behaviour was in classical.

Happens in custom too
