How does fuel (safely) get from the tank to the engine?
It would seem logical to just draw gas from the lowest point of the
tank into a fuel line leading to the engine. But contrary to a car, an airplane can experience negative gs, and especially in aerobatics, for prolonged periods of time. So a pump connected to the lowest point of the tank would only draw fumes at some point. How is this problem solved? Thanks (again) for enlightening me, Oliver |

Do any of the experimental aircraft designs use just a simple hose with a weight that follows the fuel. It's very successful in modeling. You just stick a weighted fitting on the end of the hose called a "clunk". |

In aircraft use, generally it IS a tube, not a hose. |
