Greg, I'm posting this PIC so that you know exactly what I need. I have 2 96 rails at my house that are not the right part.......lol The test port has to be on the "end cap" of the rail, and the fitting goes in the other end, and the hose runs to the fuel filter. I can only use the rail if it has the testport on the very end.

Here is a pic from corbins site that looks at the rail from the side. I have highlited the proper place for the test ports to be. That hose goes from testport to testport.

I edited to the wiki!
