Question about Automotive Site's?

Hey guy's I've got a problem with the fuel system on my 96 gmc pick up. it may just be my in line filter. But my question is . does anyone have a site that one can go to with a overview on problems and to view breakdown's on things like transmission's, rearend's, engine's,Wiring Diagrams, Ect.Ect. I've got a lot of older chilton books from the 70's & 80's. But there getting so expensive now days i just hate to buy one for just simple things. I've been a shade tree mech. all my life, i've built and raced cars but when it comes to the new style vehicles 90's and up, i need some help and pictures to get things right. any sites that you know of would help THANK"S

I’ve used a repair information page on Autozone's web site that seems to be fairly good. It isn’t as good as having the OEM service manual, but I think it is as good as the cheap Chilton or Hayes manuals that you by in parts stores.

thanks guys ever bit helps
