Can the fuel pump be powered directly from the relay board ?

Im not sure what you are asking.
If you are talking about the MS relay board it has a relay a fuse for the fuel pump so the fuel pump connects direct to the relay board. The other relays are for the 'main' power and fast idle. There is a main fuse, fuel pump fuse, and 2 injector fuses, at least from my memory thats the way the version of the relay board I have is.

Yes, you can power the fuel pump directly from the relay board. I do, and it works fine.

Any thoughts on what the most current you can sink through the relay board for the fuel pump is? I've got a 1000HP Aeromotive that I'm a little concerned the relay board won't be able to handle.
