Hi. I own a series 3 landy 88 which I've converted to twin tanks. The new tank is under the passenger seat. I've put in a brass military change over switch in the seat box & connected up all fuel pipes but I now need to get hold of a wiring diagram to complete the job so it reads on the fuel gauge. I'd be most grateful if anyone out there can provide me with a diagram please. Cheers tonypett.
