I did use injectorRx since I couldn't find any place locally. I think it was $25 irc. They have a form you fill out, with pricing info. I think a new injector was $125 or $150. I would say it is absolutely worth it. If your pump was in bad shape it clogged the downstream injector. And the ratio of $25 to what you just spent on new pumps is minimal! Downside is it took about 1.5 weeks to ship both ways. If you can find a place locally you might go with that, but InjectorRx seemed to have some info on this injector and could verify it met original specs.
