Does anyone have a vaccum hose diagram for my 1987 barth 454 engine 4 barrel carb.?

If there is no response here, find an 86 P30 and photograph the sticker on the air cleaner.

Then post it here.

With that as a catalyst, maybe others will do the same. I promise to post pictures of my 84 and probably of my previous 85 SOB.

Another resource is the smog police for your jurisdiction, or the smog testing station.

www.Alldata.com lists only vans, pickups and suburbans, no potato chip trucks. It is possible that the higher GVW of the P30 would make them different. Maybe someone knows of a better online source.

Hope this helps!

Thanks, for the picture.
