Stonesetter,

Yes, I found some vacuum diagrams on the Mitchell1 DIY/SnapOn website for this 7.5 liter engine. The Chilton manual I have doesn't cover this engine. There are two engine bay drawings of components in the engine bay and also a couple of vacuum diagrams. I was having trouble identifying all the different stuff under the hood and didn't have any pictures--which reminds me--I will take some pics and try to post them next week. I'm going to try to attach the vacuum diagrams to this thread. It will take me a little while. I decided to invest in the Mitchell 1 site for one year ($30) per vehicle. One week is about $12.50 per vehicle. They've got a lot of good data there. How's the weather in southern California? It has been raining for days up here--San Francisco Bay area-- and we're tired of it.
