Re: Suitcase fuel tanks

@Garry or anyone else In The Know..

Could you provide a little background on how this fuel system works? If there’s a (pump?) diaphragm in the tank, why would the tank need to be sealed for pressure – doesn’t it simply draw fuel from the tank, up to the motor?

Or does the diaphragm pump pressurize the atmosphere in the tank, which then forces fuel up & into the motor? I assume then that the point of the magnetic fuel gauge is that it requires one fewer pressure-sealed element piercing the tank..?
