Cali model?
I'm stripping down an old econoline engine to replace the cracked block in my 03. I have some familiarization with California models for 99.5-03. I was not aware there was such a model for the OBS, but I found a pulse damper on the fuel lines coming off of the pump, and the fuel line are obviously different! When I looked up this part to see what it was (I was a bit puzzled when I saw this part), it seems to be marketed for CA models only. I have also noticed that there are different part numbers for the EBP tube for CA models and non CA models. Now I don't have a non CA engine sitting directly next to this one to compare side by side, but I don't see how this tube would be any different than the one on my non CA engine. Are there any other differences to look for on this engine?

pulse damper was used on Cali models
I have wondered if it would help a non Cali idle better

Interesting, I thought 120 cc injectors we're used from 94 till 99.5. but I'm not an obs guy either.

IIRC the GPR shunt is different. 
other: the PCM, the FPR has a harder spring (I think) b/c the fuel pressure is already high (don't shim the Cali b/c it will wear out your pump way prematurely.
