Yes, it applies to a 1969. I also think it applies to 1965-1968 models with four tanks, and I have included a diagram of the fuel system to allow you to compare it to yours. By the way, an easier to remember address is
www.SkymasterUS.com and then select Fuel Supply Management.
On the original topic of this thread, dealing with Checklists, please note that I can send you one of these if you go to the web site address given above and then select Skymaster Checklists.
