In-tank fuel modules by size?

[I Lean]

Anyone know where I can find dimensions of different fuel modules? I need to build a fuel tank, and would like to use a factory-style in-tank pump similar to the style pictured below. I've been searching, and can't find anywhere that lists any dimensions. I'm hoping I can find some list somewhere, so I don't have to resort to going to Autozone with a tape measure, and hoping they'll let me pick through their shelves.

I need it to fit a depth of 7"-9", supply at least 50psi, and have 3 lines. (fuel, return, vent) I'm hoping to find one I don't have to modify, or at least not too much. Any clues?

My first thought was walking a yard. There are fuel tanks everywhere so it would be pretty easy to find a tank that's the right depth and then go from there. Vent and return fittings are easy to add to the tank, but you may get lucky and find a tank that used a module that had all three built into it.

I was thinking it might be hard to see the top of most of the tanks, since they're underneath....but I've never actually looked for them at a yard, so I could be wrong. I think I need a module with at least a return line, because a single-port one probably has a pressure regulator built in.
