Fuel Tank Selector Valves
 

I need to replace the fuel tank selector valve on our '84 K2500 diesel and was looking to see what valves are available. The GM/AC Delco is a 14029228 and the Standard brand is an FV5. Anyone have a preference over brands? I see the Standard is called a "universal" and says it might require a pigtail changeout. Is the Delco part preferred and not require any wiring changes?

Thanks.
