How many injector pumps are there?

[delicanuck]

Hiya,

Does anyone have a clear understanding of exactly, for sure, how many different models of injector pump there are? Specifically I ask because it seems like it would be very helpful if we could have one spare on-hand so that if someone blew a pump, they could install the spare within a day or two and then pay to get their old one rebuilt to become the new spare. If there were several different pumps, this wouldn't be an affordable option but if we all had the same pump, it might be possible.

Maybe the definitive way to answer this question is for interested parties to stick their heads under their passenger's seat's, then go out to your car and get the model number of your injector pump and post it here.
