Hi guys, I'm getting ready to tear into the fuel system and send out my injectors for cleaning (sending to RC fuel injection in Socal), I wanted to confirm some part numbers and stuff I should have on hand to replace. I'm also changing out the fuel filter while I'm in there. Car is a 97 LX450.

Is there anything else I'm missing here? Besides the insulator (G), is there another o-ring on the bottom of the injector I'm missing?

Thanks,
Yes A and B washers are the same. The part number is 90430-12026. I would recommend also buying the banjo bolt on the fuel rail.

Thanks,
Might as well get new connectors for the injectors as they will probably break due to age and heat!
