eli5 how does the car not starve of fuel when incline?
In: 0
Typically the inlet of the fuel pump is located in the center of the tank all the way at the bottom. So even if your car is at an incline the inlet to the fuel pump is full of fuel and the pump will be able to pump the fuel into the engine. With this setup it is still possible to have fuel delivery issues on steep inclines when the tank is almost empty though. However this is not seen as a big enough issue for most people.
There are ways of fixing this though if you suffer from this. For example if the inlet to the fuel pump is flexible and weighted down into the fuel then it will be able to follow the fuel to whatever side it sloshes to. You can also get a tank which tapers down to the bottom so your inlet is always full of fuel. You can also get expansion tanks in the fuel line which holds some fuel and are able to feed your engine until the fuel pump gets more fuel again.
