How can you manually run the fuel pump prior to removing the fuel tank to empty a full tank?

I assume you have a pump failure which means you cannot operate it. You need an external pump hook up to drain your tank.

No my pump isn't producing the required pressue to allow the car to run, i.E. Weak output.

Then you can power it up through the inertia switch by applying 12 volts to the wire to the pump.
