in particular, i'm trying to diagnose a BIG fuel leak on the passenger side rear of the engine. the engine valley is dry, so i believe it is not the pump, thank heavens!

I used to have a 6.5 surburban before I got the Avalanche. Rear on passenger side sounds in the vacinity of the fuel filter - are you sure the filter is seated correctly?
unfortunately after putting it up on ramps i got a better look at it, leak definately coming from injector pump.
thinking it is either a loose fitting on the return line or a leaky fuel shutoff solinoid. will know more after manifold is off. it runs fine.
it may be under warranty, i'm gonna call around on monday and either let the dealer fix it, or tear into it myself depending on the outcome of the call......

Good luck - mine drove me crazy after I put in a filter once. I must have had that filter in and out a jillion times and could not get it to stop leaking - so sent if off to the dealer and evidentally, the ring from the old filter had fallen off to the bottom of the cup and would not allow the new filter to seat properly - man that drove me crazy, then was embarrased that I didn't find that ring. Live and learn.

John, leaking injector pumps became a problem after federally-mandated sulphur content rules. It seems some other important stuff had to be left out of the mix also. So,... There is a seal that will sometimes go bad on these, because of the different fuel formula. A rebuilt pump will have an updated seal that will work with the new fuel.
Good luck with it!
