Thanks guys! I went to Napa this afternoon. The definitely have the 2" 1/8 diameter nipple. The valve is a little tougher, but I going back in the morning to talk to the "older truck" expert. Worse case scenario they can give me a valve with an adapter to get to the 5/16 fuel line.
Thanks again for the responses and the picture! I'm going to carry the picture with me to Napa to see if they have the identical valve. It appears no one makes the exact replica of original.
