I was a line service tech at a couple of FBOs back in college decades ago. I'm semi-retired and am now working at another FBO after 30 years. I vaguely remember a couple of aircraft models that if you tried to re-fuel their tanks in the wrong order you would have fuel pouring out of a filler port. I think one of those aircraft was a Cheyenne. Is that right? and MAYBE one model of a King Air?
What I mean is if you filled the outboard wing tank, and then tried to fuel a nacelle tank that was interconnected, once you opened the nacelle filler port fuel from the wing tank gravity fed into the nacelle and came spilling out of the nacelle opening. The only other gotcha I remember was the LearJets and their fuel imbalance issues, which we almost always solved by fueling both sides at the same time.
Does anyone know of piston or turbo-prop twins that fit this description? I did save myself a face full of Jet-A by remembering to depressurize the tip tanks on a Mitsubishi MU-2. What, if any, are aircraft with fueling gotchas you know about? Thanks for any help. The other line techs are college students, mostly and most of our business are based aircraft so there is A LOT LESS variety of aircraft than at the FBOs I worked in college. As of now I ask the pilots before fueling and 99% of the aircraft and pilots are "fuel it however you like".
