if you mean, the hose has already been replaced since the car got out of the factory, these are some pointers, but are not absolute:
1. the hoses don't match.
2. the hose clamps need a screwdriver to tighten. original factory hose clamps are usually simple spring clips.
3. the hose looks very new.
4. someone confessed to having replaced the hose.

but if you mean for signs, that one needs to replace the hose:
1. there is an obvious leak in that hose.
2. there are cracks on the hose.
3. the hose feels soft. (this is subjective. one has to have had some experience on how soft it should not be.)
