Default Re: Fuel Line, Shut-Off Valve to Firewall: Why Made Of Hard Steel?

Guten Morgen, that's no reasons to quarrel!


At that time, machine construction was oversized. A great safety factor was built in. In case of doubt a number stronger.

You hardly had to pay attention to the total weight and the material consumption was hardly limited.

Due to the known vibrations and the risk of fire, a fuel steel line was used that was considered to be particularly safe. Because the frequent opening and closing of the often tough fuel tap resulted in additional stress. Especially since at that time pieces of cargo were also loaded on the floor.

There are many other examples. The suspension of the axles, the powerful pedal shafts, oversized crankshaft bearings, thick piston skirt, ...

"Lightweight construction" was unknown in the 30-th automotive industry. It only started gradually with the self-supporting body with sheet skin without a frame.
