Where to put FI pump

[lr172]

I am converting my 6A's O-320 to FI. I was going to build up a filter and pump system from parts, but I think I have decided on the AFP pump unit. Just curious where you guys put this on a 6A. It doesn't seem that I can mount it to the spar with the leg mount there. Currently thinking that I will attach it to the floor (center). Thinking someone out there came up with something creative.

Thanks,

Larry
