    Hi All,

    Does any one have the part numbers for the fuel injector O-Rings?

    Is it as below or different? It is kind of hard to find it from the website.

    2325551010 - Bottom (big ones at engine)
    9030107037 - Top (small ones to rail)
    O-Ring #9030107037 | Autoparts.toyota.com

    Also how to find part number for this? The link above with part number 903010737 shows this diagram and the number shown here is 23250B. How are they linked together?

    Thanks

    Just bought 9030107037 X 4 from the local dealer with VIN provided to match it. Hopefully i can find the part number for the bottom ones (or i can reuse them). Bottom ones looks to be "ok" .

    The reason to remove them was to clean it and replace the micro filter. Micro filter removal needs a special tool, so just cleaned from both side with power applied. Not sure how well it clean it. Also was able to damage one injector while trying to remove the micro filter without the tool :(. Now need to buy one injector also.

    The top ones are leaking. As per manual, i put some gasoline in it and twisted it in, but seems damaged. Bottom ones look fine.

    yes. Trying to get a junkyard one now. Will update later.

    just dip it in gasoline and push&twist? The service manual specifically says do not use oil. Says to use gasoline / spindle oil.

    No mention of spindle oil? That said, gasoline is much easier to come by.

    what’s “it”?
