Title: 1983 K20 CA 350 (Vin M) Vacuum Routing
Post by: RHershner on August 12, 2020, 01:31:23 pm

Hello All - new to the site and haven’t found what I am looking for. My ‘83 K20 has a 350/700, it’s a CA truck but 8,600 GVW (so federal emissions apply). The vacuum diagram on the air cleaner is burnt off/missing and I’m having a heck of a time finding it. This truck has the heat riser, EFE, TVS but *NO* EGR. Can anyone help? Pictures, diagrams or anything helps me out!

Identified the TCS off the p/n and confirmed but it wasn’t routed to the distributor so now I suspect everything.

Thanks in advance!
Rich

Thanks! I’m pretty sure I have the WF routing.. any ideas where I can get a reproduction sticker to put back on the air cleaner?
