Diagrams: either buy manuals from Helminc.com or search here and Google and cross your fingers. The Helms books are specific to vehicle and year, so be sure to get ones for the right application...things like connector pinouts tend to vary year by year.

Someone here at some point posted about finding some subscription service at their local library which had the same info (free), search on this forum and you should be able to find it.

Fuel pump: eBay tends to turn up a few of these, just get into the Parts, Car and Truck section and do a search on 'LS1'. I used a Walbro 340 from autperformanceengineering.com as it was a direct bolt-in for my project car.
