Are the fuel pump brackets not all the same for the 18.5 gallon tanks? I picked up an Airtex bracket/sending unit and a Walbro pump and they don't fit together. I would like to get this figured out before next week so I can replace it.

I see that this has already been analyzed to death (http://www.shoforum.com/index.php?threads/slight-problem-with-new-walbro-fuel-pump.113683/page-1) so now I have to see if I feel like shoving in the wrong pump is acceptable, or if I need to buy the 526 pump.
I thought at one time SHO Source had plans to start carrying the 526, since it's the one that fits properly. People buy the 516 thinking they are getting 15 lph higher flow, but that's untrue. The two pumps are identical except for the shape of the plastic end piece. Walbro engineering said there's no difference in flow.
The pump is Delphi/Walbro fe0115 (25176210, E9DZ9H307A, F0DU9H307FA, F0DZ9H307C, F1DZ9H307A, F3DU9H307DA, F3DZ9H307D, F3DZ9H307DA)
The bracket is SPECTRA FG29C (F4DZ9H307B)
Thought it was an Airtex
