Pressurized fuel tank

[Tom the Blacksmith]

My 1906 car runs with a pressurised tank, as Greig says at cap that seals well is essential. I called in a favour with a mate who has a flow rig for (old) aircraft carbs to check what pressure my 1st gen zenith works at, 1psi in my case. Once pumped up, it only requires a half pump every now and then to maintain pressure. There's a tap to release pressure when you stop, otherwise it gets a bit incontinent .
