Most installs don't need the hot fuel module. I installed a TBI 350 in a '83 malibu (my first efi effort) after 1 week I tossed the hot fuel module.
Normally the orange wire (power feed from the battery)to the fuel pump relay has a 20A fuse in series with the relay. My GM manual shows a 20 amp fuse.
