Frank,
I saw your post on the rv7-list but didn't reply because I didn't have exact
dimensions handy...and in fact, it will vary from aircraft to aircraft based
on sweep.
In my particular case, the distance between the fuel tank and side skin
starts out around 4" at the leading edge and tapers down to about 3" at the
spar.
I've definitely seen people mount boost pumps in the wing root, claiming
that it's much cooler for them there (and I buy that).
Do a Matronics RV list search (http://www.matronics.com/searching/) for
"pump & wing root" and you'll get a buttload of info on the topic of fuel
pump installation. I don't recall where exactly I saw photos on the web of
wing root pump setups, but I know I've seen 'em out there before. You'll
have to work some tubing magic, but that's not a big deal.
If it's any consolation, the standard AFP high pressure pump install kit
that Van's sells worked well. My pump/filter is located right in front of
the selector valve. It doesn't get in the way of our legs and stuff, but it
does introduce a lot of fuel connections into the cabin area. FWIW, I've
had various tiny oil leaks and brake fitting leaks in the past, but the fuel
system has been dry as a bone.
In a way, I'd almost rather have the leak in the cabin than outside.
Outside I'd never know about it until I was on the ground. Inside, I assume
I'd know about it right away.
Best of luck,

And in case it sounds like I've got a "swept wing" RV-7, I don't... ;-)
It's due to the curving contour of the fuselage.
