Hello experts, I just bought the titled vehicle and a few problems are 1.duel fuel tanks do not switch over, switch front rear seems to work. 2. fuel guage does not register, will just rise from ign off to empty when ign turned on. Seems odd that both sending units would go at same time. Any chance of e-mailing me the wiring diagram for dash to sending unit and switch. Do and I'll have a cool one for you on my newt camping trip. Thanks Tom.
