Can you PM me a pick or 2 of the pump?

I may or may not have taken up this solution. They only check that it is installed. I do have a modern high-flow cat (Magnaflow) in place of the stock pancake converter. It is actually super clean at the tailpipe.

They would base emissions on the year of the engine. If I installed a 2016 LS engine, then the LS's emissions equipment would all need to be intact.

I'll go look when the weather breaks. If it will work, you can have for the cost of shipping

Also is it a Federal or California emissions pump?

You can also look on car-part and Hollander parts locators and maybe find one local.?

Thanks! Yes, that is the vehicle. I just need to get it through this round then I have a year to figure out what I'm going to do. I might be ready for the diesel swap by then.

Also looking at classic/collector car insurance - vehicles here are exempt from emissions if insured as a classic/collector.
