Default Fuse sizes?

Friends,

Making 2 mods to beat the heat...

First, I added a dual pusher rig from Acton (I know, more for looks...) BUT, I'm using the original Kirkham circuit which had a Spal puller, rated at 20A, with a 30A fuse. The pusher motors are rated at 4A each. So, how should I fuse them? 15A, 20A? (I used the original circuit for the pushers because the new bigger puller requires a more robust, discreet circuit).

Then, I replaced the original Spal puller with a H.O. Spal 30102113, rated at 26A. I ran a separate circuit with a 70A relay and heavy gauge wire. So, the fan runs at 26A but Spal recommends a 30A fuse, believe it or not!!!??? Shouldn't it be 40A? I know I can test it but isn't there a safety factor built in to the size fuse used?

Aside from hearing me ramble about my evil doings, how would you protect 8A and 26A (running) respectively?

Thanks!
