Once below 28L or so total the right side effectively is empty. It should register about 1.4L on level ground.

When you accelerate or turn all hell breaks loose with the floats thats why the dash uses a buffered value.

A firm right turn will spill more than normal fuel from right to left and can eaisky register 000L for a bit until the siphon jet sucks some fuel from left to right.

If on level ground the right side drops lower than the 1.4 ish, then you have siphon problems and need to address it.
