Hey i don't know if anyone posted this report earlier, but since 1.0 Rapiers and all Jet engines uses their fuel source equally of the whole craft even these things aren't attached with fuel lines and because of that KER doesnt give the right amount of DeltaV out. It "thinks" these fuel sources aren't consumable, but the Rapier and the other Jet engines can reach it. I just want to help to notice the error Thank you for listening PS: If the error was reported before i apologize
