TPI fuel tank?

[tipshep]

Thinking about installing a TPI in my 72 GMC, mild 327 etc. Wondering on a fuel tank to use. I have a factory unit with return lines, etc. behind the seat. I was told Jeep Cherokee (the small 4.0L) tanks work well in the pickup, have the F.I. pump,so on. Also, may check the small Blazer, maybe the Tahoes, etc, not sure where they mount. I'll measure and go to the local pull a part. Don't want to do an inline pump, they don't last as well. Curious what others have done.
