I tried using a 30 amp inline fuse on my race car(with HEI) once, and it popped & banged at high RPM (around 5500-6000) for a few laps, then finally blew the fuse. I rewired it without the fuse and it ran great. I'm not sure what you need, maybe a fusible link, or a breaker, but a 30 amp fuse won't do it.
