My question is that the fuse related to I believe the fuel pump only last 10 minutes and then it blows.
Can you help me to figure out where the short is? Thank you.

Are you talking about the ecmb fuse. That also sends voltage to the computer. If you can find the fuel pump prime connector, you can run the pump by itself, using an inline fuse in the jumper, see if the fuse still blows. I think a 10 amp fuse should run the pump by itself. That prime connector may be close to the pump relay. I don't know the exact location.
