You didnt note what you jumped at the relay to make the pump work. Depending upon the year of your car/harness, the inertia switch is either on the control or load side of the circuit.
On earlier models, the link for the load side is 18 gauge, connected to an orange/lt blue wire.
Simply stated, if you have one terminal at the FP relay with constant power and another that shows key-on power, the links should be ok for the circuit.
