Agreed, there is a distinct possibility that the fuel pump is faulty. It's fitted inside the top of the fuel tank which also incorporates the fuel sender unit.
You will need to drop the fuel tank to get to it and then undo the slip ring for the sender/ Fuel pump.
The Haynes shows the unit the 2 plastic fuel pipes, I have found they are usually very difficult to separate from the sender. They are of a similar type to that attach the fuel lines to the filter. Squeeze and pull being of the quick release variety
It is possible whilst the car is up on axle stands to carefully lower the tank after first disconnecting the pipes connecting the fuel filter.
Carefully lower the tank with a block of wood and then unplug the sender unit connector , before it get's strained & damaged.
With this unplugged, to rule out a wiring short replace the fuse and turn on the key to get the battery light on etc. If the fuse doesn't blow , the wirings ok You will then need to chisel the large ring anti clockwise to get the unit out.
Before removing the slip ring and unit from the tank, inspect the white wire connector on top of the sender/fuel pump unit. It may just be heavily corroded or suffering from water ingress. Clean up the terminals & spray with WD40 Perhaps this occurred after driving through heavy puddles. You will be amazed at the corrosion and water that sits on top of the fuel tank and rots them out.
If the connector was corroded / wet reconnect filter fuel lines and plug connector in Replace fuse and see if it works without blowing. If all's ok rebolt the fuel tank. If the Connector looked clean. then you will probably have to change the sender fuel pump.
