So far loving the carter. Also went with a carter oil pressure safety switch. Was chasing a gremlin with the pump getting power then not. Then not cutting off when the truck did etc and ended up being two faulty Napa units back to back. Perhaps I just always get bad napa electrical components so not sure why I keep giving them a chance as not the first time their stuff as sent me on a goose chase. But since replacing that with a carter unit it has been working exactly as expected! In terms of reported noise I can’t say the carter is any louder than the Carbole as some others have reported. Could be my hearing though.
