Thank you for your reply. The fuse was blowing as soon as it was installed into the fuse holder.
Using your advise (and several fuses) I was able to find the problem.
I disconnected the wire to the fuel pump and the fuse still blew.
I traced the wire from the fuse back to what appears to be some kind of relay behind the choke.
I disconnected the wire from the 'relay' and the fuse did not blow. The output of the relay had several wires. One goes to the fuel pump and one went to the choke and I could not find where the other went.
I disconnected the wire to the choke and reinstalled the wire from the fuse to the input of the relay. The fuse did not blow. I figured the choke was the problem and was getting ready to replace it.
For kicks. I reinstalled the wire to the choke and the fuse did NOT blow. So now all the wires were connected and no blowing fuse. Strange. I figured the problem was intermittent.
I started the genny and it fired right up. I let it run for a bit then I grabbed the wire from the fuse to the relay and gave it a shake. Sparks began to fly everywhere.
The problem was the wire was not properly shielded/covered and it has been rubbing on the chassis. The wire insulation finally wore away and the 12V was shorted to ground. When I was fiddling around disconnecting the wires I must have moved it so it was no longer grounded. Problem Solved. I rewraped the wire and put it in a plastic wire loom to protect it.
If the offer still stands I would really like to have a schematic for future problems. My model is 4BGEFA26100M.
