Finding smog pump 1985 Chevy K20

ihtblzr · Oct 10, 2024

Update: We sold the vehicle out of state so not worrying anymore. I do like all the people on this site!!!!! 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?

hoagster · Oct 10, 2024

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

Thankyou

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:

Im trying to convince him to move. I agree with you.

So I took some pictures, Like I said my truck is a 73, This is what I have. Hopefully some one will @Old60Driver @fast 99 will take a picture of there setup.

You must be registered for see images attach

Does he have everything else like the picture above? The tubes on the exhaust manifolds. All of this has been sitting in the barn collecting dust as you can see And spiders.
Hopefully someone will chime in with more guidance as to whether these will help you or not. If they will we'll figure out how to get them to you.

My husband thinks it might not be the right one as the pulley looks larger. Will hopefully gets some input from the people you tagged and in meantime will do research into. I do appreciate you doing this. Update - looks like it may be right one as it has same number on the back as the number cardone shows on there’s(which they don’t have) . So worth a try and we are in N Ca so how to get and costs?

Looks the same as what I have on my 81
