Does anyone know if it matters how the pump is bundled back into the guts of the trunk?

When I got it last fall, it was a mouse nest heaven and everything came out for washing/ gutting and I forgot to take a picture of how this was stored.

The sound deadening foam was saturated and tossed in a frenzy of disgust. Now I can't find any dimensions to remake and I don't remember how it was secured.

This was the only item I could find on ebay that had a picture, but i don't need to buy the pump.
