GC,
I did not see that the air pump is different, but I noticed that for the other emissions items it seems same for 90-91 and 92-95 for all the a.i.r. stuff. It seems the same part number for the air pump itself so that is good news if true. Wow, we really have to check about some of this specific MY stuff and I guess there are ways to make interchange on something and not others.

Im referring to the secondary pump. The pump is the same but the connectors are different.

good stuff!

Just wanted to share a few things I just found out.

1. Marc H said this does not apply to MY 1990 with the cannister in the front.

2. Standard Motor Products CP1032 does not work for MY 1990 and does not have the port on the bottom of the cannister like the factory unit.

AC Delco 215-155 and GM 17113150 that is supposed to be for MY 1990 is being confirmed and will pull out the factory unit to see what part number is actually on it.

Craig, because our 90 M/Yr canister is 'right side up' our charcoal can't get out into the lines? Do I get that much?

Thanks for running this down for the rest of us 90 owners!

Tom,

I don't know about the cannister and why no issue with MY 90, just what Marc H said. But it does sound logical. I don't know if I really need a new one or not, but trying anything to help pass emissions and it is over 20 years old regardless.

My main concern is that no one else buys Standard Motor Products CP1032. I found the problem and wrong cross reference given by Rock Auto. The part number on the item is GM 17092089, Standard cross references it correctly as CP1032.

I'm not sure if AC Delco 215-155 or GM 17113150 is correct and I assume so since the parts catalog for our cars states so. The problem is I can't see any good photos where it shows the bottom of the cannister with the port and connector. I just found and ordered GM 17113150 so we'll see when it arrives and I'll report findings. My Hawaii blood is too wimpy to go out in the cold garage right now to pull out the stock unit to check. It might be possible to see the GM part number but it is a little tucked under that corner. More to follow..............

Okay, so the cannister that is in my 1990 MY is GM 17087214. The thing that sucks is it does not seem to have a cross reference to AC Delco and when going to Standard Motor Products cross reference the have going to CP1032 again...............

Now my question is why the parts manual for our cars has a different part number and no where does it reference GM 17087214? Oh well, another 1990 part nightmare.

Looks like another case of NLA? I'm thinking that other than the mechanical parts, valve & it's solenoid, what are the operating parts? The darn charcoal is all I can think of?

In a worst case situation if the part is NLA. What about going to an HVAC supply house and getting a bunch of filters that have charcoal impregnated into the media and doing surgery to do a swap out? Or, I just had this BFO, some fish tank filters use granular charcoal, why can't that work?

Okay, I admit I'm out where the buses don't run!

...and if the buses did run out there, the driver wouldn't stop for you

Does anyone know if a ? standard 88-89 vette canister is different than a Z?or what about a truck.? Its just a can - maybe they will be the same.. Or like tom said - cut it open and replace the coal..
