Fuel Gauge Fuse Keeps Blowing!

Ok So I picked up the 280z Today! YAY!

Drove beautiful, Over heated in trafic a bit but not to woried about that! what wories is that the car dies out sometimes at idle when stopping! So once it fully Stopped and wouldn't start at all! After I took it home it was a link that was burned out it was in a box right to the battery covered by a white square top there were two wires in there well one of them burned out which was the reason the car wasn't starting!

But after that incident the cars RPM gauge and the Fuel Gauge don't work anymore and the Fuel Gauge fuse keeps blowing!

PLEASE HELP!

The car starts and runs but the fuse keeps blowing!
