I had an 84 K20 HD gasser with the factory outside the frame rail saddle tanks and I had to replace the dash switch. Been so long, but I think I simply used a paper clip between the switch leads to verify it was bad. Test the simple stuff first before digging into the solenoid(s) that switches the tank lines.
