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.

Actually that is a good point...I had a cracked fitting inside my cabin
and hardly any fuel leaked but it stunk to high heaven...:)
I was just terrified it might burst into flames before I got it down....

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,

Yes its probably OK with the 3/8ths fuel line but hydralically the best
place is "out there" and I do like my current A/C setup which does the
same thing and I switch taks by simply switching pumps...Works real good
and you can remove the engine pump which...yeah ok it does'nt require
electricity but is very prone to vapour lock too.
Besides each of the Lightspeeds need elctric too...:)
So for me if it will fit its worth forcing...:)
Thanks
Frank

Hey Frank,
The distance is about 4". Just to let you know (and I'm sure someone
will have an opinion about this but) I am running auto fuel in my 7A
with the standard boost pump from vans in the normal location (inside of
firewall) and I have 60 hours on the plain now and have had no trouble
with vapor lock. I run 93 octain fuel from BP in a 0-360A1A. Not a bad
idea to put it in the wing root for if anything piece of mind. Have fun.
