It depends how far back you're going to splice into the fuel line? The manual itself on the theory and operation of that fuel system states the following: "The fuel pump flex pipe acts to dampen the fuel pulses and noise generated by the fuel pump." If you don't go back as far as the flex pipe you will probably be okay. It's hard to be a psychic mechanic. If you are still stuck tomorrow let me know and I will run down to our local wrecking yard and look at one of those vehicles for you and see what we can do to repair it.

FUEL SYSTEMS > FUEL DELIVERY > Fuel Pump
The fuel pump is mounted in the fuel sender assembly reservoir. The fuel pump is an electric high pressure pump. Fuel is pumped to the fuel rail at a specified flow and pressure. Excess fuel from the fuel rail assembly returns to the fuel tank through the fuel return pipe. The fuel pump delivers a constant flow of fuel to the engine even during low fuel conditions and aggressive vehicle maneuvers. The PCM controls the electric fuel pump operation through a fuel pump relay. The fuel pump flex pipe acts to dampen the fuel pulses and noise generated by the fuel pump.
