Air Valve

Short: Air Valve

A second interesting discovery: the fuel filler cap, located inside the cab, has an air valve on it.

These vehicles were not equipped with a fuel pump, which means the only way to get the fuel from the fuel tank under the seat to the engine was by gravity. Which meant, in turn, that the engine had to be lower than the fuel tank. Which meant, in turn, that if this truck were going up a hill of any length or steepness, it would have to go up backwards. Now, a recent museum visitor did point out that such a maneuver might actually be a good thing - if your brakes failed, at least you'd be careening down the mountain forwards. But it still must have made things interesting for the Derry brothers on their berry-picking expeditions up Thompson Mountain.

The discovery of the air valve changes the picture a little. It looks like it was meant to be attached to a hand-operated air pump, so, in theory, the driver could keep enough pressure inside the fuel tank to keep the gas going to the engine, even up hill.

Between the air pump, hand-throttle, gear shift, hand brake that forms part of the clutch mechanism, brake pedal, clutch pedal, and steering wheel, I think you'd need to be somewhat of an octopus to drive the thing. But at least you'd be able to see where you were going.
