I am sorry, but I cannot understand what you have typed.
To get a good idea of the damage, put the car on the lift/ramp and check it yourself.
I am not sure of any fuel sump.If it is an oil sump, it needs to be changed immediately if it has a crack in it.You can look for oil spots where you park your car.If the oil sump is leaking the engine oil will leak away slowly/fast depending on the size of the crack and your engine will cease.
The gear mount assembly is a crucial part as well.This is what the gearbox rests on.
If you have any doubts, get the car assessed from a local mechanic and if he gives you the same prognosis then get the car repaired by him or if it is under warranty get this done at the authorized service center.The gearbox mount should be covered under warranty.You can find the details of the parts covered under warranty in your owners manual.The oil sump must have hit something and hence won't be covered.But to get a good idea of the damage, put the car on the lift/ramp and check it yourself.
