need to upgrade fuel capability

Been trying to get info on what all I need to upgrade the lines and rails but no luck.

I know I can get rails with adapters to fit the stock lines. But is that really gonna do any good?

I know I can get AN fittings with braided line. But how do I connect to the tank lines/fuel filter?

or do you have to go all out and get sumped tank,lines and rails all at once?

thanks, I've checked out Glenn's site several times. That's why I was wondering if I had to do the whole system at once... their kits get pretty expensive and they don't include rails.

how did you wire your external Walbro's? Wiring makes me feel uneasy.
