Trying to find a smog pump and diverter valve for a 1985 Chevy 3/4 ton K20 350 to make smog legal in CA . Non computerized. I’m trying to help find for my husband so hope I asked for the right things. I have looked online and can’t find and junk yards around here don’t have. Any help appreciated

I may have some smog stuff for you! But it will be off a 1973!

may not help hopefully someone else will chime in. Your truck should have a listing of what was installed, there is a sticker usually in the glove box, take a picture of it and post it.
you will get more answers. also post a picture of the engine bay and the truck. We all love pictures

Are they inner changeable?

Don't know and the brackets could be different!

Mine would be for first year of that pump!

I took the smog pump off of my '83. I'll see if I can dig it up, and get some pictures

Be sure to check the one-way valves mounted on the air pump tubes. If those go bad exhaust will burn up or melt other items in the system.

I used to have to install the smog pump and exhaust header tubes every 2-3 years for registration smog and remove it again after I passed the test, when i lived in Commiefornia. Glad I moved to a free rural state, back to America, where we have No Smog tests :anitoof:
