Ok, I think I'm with you on this. Is the engine in post #48 your engine? That blue Tahoe is a 2002 or older, since it's got a cable throttle body, and in 2003 all trucks went to DBW. The pic in post #48 is a DBW engine and also has the bigger case alternator that the Tahoe does not. Right on the front (upper left of where the intake hose goes on) of the throttle body is a small circle with a number in it, what does it say? My guess is it's going to be a '03-04 flexfuel engine since it has the return style fuel rail.
