Dorman 800-123 http://www.dormanproducts.com/p-49076-800-123.aspx?origin=keyword
I found mine on Amazon in a 2pk 10.71 shipped. You can also order at auto zone for $11.95
This package says Ford but all my measurements says it will work. I used a 5/16th drill bit as a measurement tool both the oem and dorman o-rings were the same size. A 31/64 drill fit both openings to the seat, the o-ring distance to the seat were the same and the seat to the clip were the same, I had to be creative to measure this one. I have not put mine on as of yet, I will when I re-plumb my heater to make the fuel pump more accessible.

MrNomer has been addressing this issue. There are two versions--the one 800-123 you referenced with retaining clip like our original and the 800-081 with "quick connect." Dorman tech said they are interchangeable. I can get the 800-081 tomorrow as opposed to next week for the 800-123, so I ordered the 081.

These appear to come in two sizes--5/16" and 3/16". MrNomer measured 1/4" for our gasser, so we are gambling a few bucks that his measurement is wrong. We'll find out tomorrow.

I installed mine the clips on the 800-123 are for a one time install but can be removed. I did break one clip, good it's a two pack, but replacement clips are easy to find. Attach tubing to the 90degree before attaching it to the tank. That was my mistake and broke the clip pulling from the front rather than pushing from the back to remove the 800-123.
