Fuel Tank Switch
I have an 6.9 87 F-350 with dual tanks. The front tank is working but will not switch to the rear tank. When switched to rear it keeps running from the front tank. Other than the switch itself is there anything else it could be?

Slight hijack, but still somewhat relevant.
I have been told I should replace the O-rings in Fuel Selector Valve. 6 in all I believe. But I cannot find the O-rings at any of the parts stores. Any ideas for a source?

What does it sound like when it switches, or working properly? Ive heard it makes a buzzing sounds, but mine just kind of clicks? Could you clarify a little on the sound?
