Wing tanks fail to feed Left or Right Engines.
Wing tank pump fail lights and test are INOP.
Wing tanks will draw fuel from the main tanks when in the Refuel position, though at an incredibly slow rate.

EDIT: I have the same problem.

I just did a bunch of testing and cannot get the wing tanks to supply my engines under any circumstance. I’m hoping for a fix! (And also the glitched doors but I’d prefer the tanks to be fixed first haha!)

Do you have the same issue if you follow the OP’s steps to reproduce it?
• Yes, exactly the same.

Provide extra information to complete the original description of the issue:
• Wing tanks never feed into the main engine, making them effectively useless and limiting the DHC Twin Otter’s range since we only have access to main fuselage tanks.
