Mike,
  1. Lift the rear seat cushion and place your voltmeter across the fuel pump terminals (wiring colours as advised by Vitesse).
  2. Turn on the ignition. Does the pump run for about two seconds then stop?
  3. Operate the starter motor. Do you see +12v continuously at the fuel pump?
  4. With the engine running, watch the voltmeter closely for any interruption to the supply. You should also clearly be able to hear the pump running.

This will fully test the fuel supply system at the tank. Fuel pump failure is virtually non-existent on the petrol engines so the object is to avoid wasting any more money replacing parts which are not faulty.

You might also try my previous suggestion regarding the fuel filler cap. This is to test that the tank venting system is working properly.
