About 3 months ago I tore my L98 down for a rebuild and I'm finally getting it together again. As I took it apart, many of the hard plastic vacuum lines were very brittle and broke apart plus it's been too long to have a clear memory of where everything goes. I was wondering if anyone has a source for a decent schematic diagram of the vacuum line layout? It would be REALLY helpful! (for an '88 L98 if that make much of a diff)
Thanks,

I take it that the Vac sticker on your fan shroud isn't detailed enough? I have an 88 IROC that I just got back together and I went by the sticker diagram. I ended up getting a Shop Man from Helms which has better detail for the the lines.
Chilton & Helms huh? I guess I should go to the library and see what they have. I have a Pontiac TA factory service manual (from an '86) that has most of the info so I've never looked at the more generic manuals. Oops.
Petemed: those poor radiator stickers have long faded into oblivion ...
I'm doing an engine swap with my 87' L98 and I didn't get the strickers. As far as diagrams, I'll try the local library. Anyone else know where I can get the diagram??? DONT get the Hayes manual. There is no diagram in there.
