Tanks Inc question

Has anyone used the Tanks Inc tank, pump, and sender for EFI. Everyone talks about them but need to know if they like it after putting one in (fit). I need to return the FITECH fuel command centre because there's just no way to fit it in. I have some some things moved around and added in the engine bay and all the space is spoken for. I've got a week or so to return to FITECH so need to make the decision quick, don't want to cut my newly painted inner fenders to make room. Yes I've seen the pics of the installs but wont work here.
Thanks Larry
