That should be for the TBI engine and yes, I believe the TPI is different.

I think this is for a TPI unit because my canister is on the driver side

Re: trying to locate where a vacuum hose goes from evap canister,please help

Since I'm using and open element air filter I guess I don't need the IAT sensor and motor, should I be able to just cap that vacuum port off on the TBI unit?

I don't see why you couldn't and I don't think there is any difference between a stick and automatic where it comes to the Evap system.

I saw that video of you starting that 383, maybe one day I'll rotate the LO3 out for one of those. Since this is my daughters' first car, it'll be a while-she loves it.
