Much better - can not clearly read the tape but it looks like about a metre long.
The Weatherhead tag confirms it it American but AN6292 is standard non metalic hose used on many aircraft so that is no help.
A couple of the inspection stamps look Douglas but I cannot get any more that that at present.
One stamp is the standard American Heat Treat stamp so again no help.

One other stamp is vaguely familiar but my memory is not telling me what it means. Being six digit part numbers if it is Douglas it will be pre- or early WW2.
I will keep thinking on it
