No power to either wire.
Fuel tank changeover switch.
Fuel gauge responds.
Test light however finds no hot wire but diagram indicated two
One for gauge sender
One for L/R fuel pumps
Purchased Leyland factory manual xj6 1977- on..
Also a color coded wiring diagram
Neither portrays the fuel pump relay switch you described.

Answer
Hi David,

I don't have a diagram and just guessed that it has a relay as I never seen a car with an electric pump that didn't have a fuel pump relay. Take a photo or scan the wiring diagram in your manual and I will see if I can help diagnose the problem.
