HELP - Where to mount fuel pump..?!

Thx for the responses, guys.
It's strange that this question has brought so few... as it appears I'm not the only one with the same question. I'll (we'll) figure it out. I'm told that mechanical pumps (like the electric) don't 'suck' fuel either, thus if they're gravity fed too, how the hell does that work..?...ie: fuel source lower than the pump (= gravity fed) BUTthe pump is in the engine well on the engine, above and well forward of the tank? How does my Holley Black pump get fuel, since it's mounted above the rearend and well ABOVE the gas tank. Gravity fed..!!? I'm confused.

Whatever I do, I'll flip some pics in here...maybe be the first one to ever do it in the history of FABO! Or so the lack of responses here would indicate.:banghead:

Thx all ~
