Hitachi actually makes the OE fuel injectors for these engines, so I would go with them.
Thanks smj. I'll replace all six with Hitachi. That inside knowledge will save me about $180.00. I was resigned to buying the Denso brand simply to not take a risk.
And per your suggestion I'll replace the fuel pressure regulator as well.
Several fuel injector plugs on the wiring harness are brittle so I'll probably splice in new plugs on those. I'll take a look at Pull-a-Part for a complete fuel injector wiring harness, but it is unlikely that I can find another old one any better than my old one.
It is tempting to go one layer deeper to replace the knock sensor, but I read about a work around from someone who bolted a new one on top of the intake plenum. If it's ever necessary I think I can do better than that by attaching two, one to each side of the cast iron engine block. (if I think about it, probably only need one. It's unlikely that the engine would "knock" only on one side.) But with luck I'll never have to do that.
I did read the forum guidelines and had searched for helpful prior posts, So I had seen your advice about the blue and black dots, but I could not find anything about comparing Hitachi with Denso injectors. That's a real money saver.
Thanks a bunch! I really appreciate your commitment to these fine vehicles. (and you too VStar!)
All for now... coffee break is over... back on my head!
