I decided to take a chance and order a 79 and later fuel pump from AutoZone to have on hand should mine die. This is what I got for $70 shipped to my door. The invoices in the box showed AutoZone ordered the part from Airtex the day I placed my order with AZ. Once AZ received the part they shipped it to me. It would appear this is not a normally stocked item in the AZ warehouse. I guess there is not a huge demand. 
The directions cover the insulator found on 1/79 - later trucks very well.
The pump looks just like what is on my truck, which I believe may be the original pump. It comes with two gaskets and is Made in Japan.
