P0328 repair, dropped injector seal. Part number?

Came back from a trip and had a P0328 code for knock sensor bank 1 high input. Sure enough, rodent chewed through my knock sensor wire.

As I was taking the lower fuel rail off, I accidentally dropped one of the injector o-ring spacers. It the hard plastic split washer that sits directly on top of the lower injector. It’s flat on oneside and concave on the other.

Does anyone have a part number for this? Maybe even the whole seal stack (from bottom to top: plastic split washer, large black o-ring, small blue plastic stopper)? I’m in this deep and don’t want to tear it all back apart if I messed up a seal.

Thanks for the link. I’ve searched through that page a bunch but I’m not sure what the correct part number is without a diagram or photos. My best guess is its 23256-31010, but I’ve seen a similar looking part pop up under 23258-31020 (and other 23258- part numbers)

 

Usually if you put your vin in depending where you order it they will get you the correct part. McGeorge Toyota does that for me as well as toyotapartsnow. Not sponsored or plugging any one dealer just going by experience

 

Resurrecting an old post but I'm in same situation looking for these parts. I will post back as REF when I find the correct part#'s for the stack. OEM only


Here is the lower injector stack parts for future ref...
23256-31010 : Ring, Fuel (as shown in post above)
90301-05011: Ring, O
23258-31020: Ring, Fuel (the blueish top ring in the stack)

So far the best schematic yet for me...
