[H. L. Chauvin]

I had a copper fuel line from the Model A fire wall to the carburetor.

Because of constant vibration, generated heat, & metal fatigue, while working the copper fuel line back & forth, the copper hardened and fractured at the connection on the carburetor end & leaked gasoline.

(This fracture occurred in about (2) weeks & resembled taking a steel coat hanger, working it bach & forth in one short area until it breaks).

Next, I provided about a 6" diameter loop in the middle of a longer new copper line so that the copper line's loop could flex over a large area & it never broke again.

I saw someone's photo on this Forum sometime ago, of a loop provided in a Model A copper fuel line from fire wall to carburetor.
