Saw the same “pretend to be a journalist” trick in a free Reddit post from 2022, so yeah, you got fleeced.

That line rubbed through where it was clipped to the frame rail" is the exact kind of thing that makes me question why we trust aftermarket parts so much. I've seen the same pattern with fuel lines and wiring harnesses, stuff that's supposedly pre-bent and ready to go but ends up sitting against something metal because the clips don't line up right. You'd think after 50 years they'd have the routing down, but nah, they just stamp it out and call it good. My buddy's 78 Ford had a pre-bent brake line that wore through in under a year because the metal tab they used to hold it was too tight and vibrated against the frame.

Totally fine for older cars" is what I used to think too, until I had to replace a fuel line that turned into soft gummy rubber. @thomas862 you're right that the carb seals are the first thing to go, but I've also seen it eat away at fiberglass gas tanks on some old boats. The ethanol just attracts moisture and causes all sorts of corrosion problems over time. I won't run anything with ethanol in my small engines or classic vehicles anymore, it's just not worth the headache.
