    Well, after 265,000+ miles the fuel gauge sending unit finally crapped out.

    With the high mileage involved I figure it's best to replace the entire assembly versus trying to repair it.

    Looking online, dealers are in the $600 range for an OEM replacement. Aftermarket is slightly cheaper for a known brand name such as Delphi and Carter.

    Are there any other recommendations I should be looking at or just bite the bullet and go with OEM?

    I would try and find a Denso fuel pump assembly, Denso is the OEM supplier for Toyota, you get an OEM part but without the Toyota name on it or the Toyota price.

    I recently did the the fuel pump and sending unit on my 2004 4.7, not the entire ‘assembly’ though. OEM Toyota parts for both. It was like $300ish for parts and $300ish for labor. Now fuel gauge is working flawlessly and I have a new fuel pump. Just another option besides doing the entire assembly.

    I have read that the plastic carrier has a secondary internal filter. What did you do about that?

    Ok sorry, for one I was off on my parts amount and two I did purchase the filter as well… here’s what I bought:

    (the ignition coil was just to have a spare one on hand)

    Labor was $363 if I recall.

    Had my fuel sending unit replaced in June 2022 and did the fuel pump for good measure while the tank was out. from the other forum has a lot of info that may be helpful.

    That secondary filter was my concern. They don't show up as a separate component on the parts breakdown.

    The p/n for the housing is in my post and it’s not very expensive.

    So...
    Fuel pump and strainer kit...$130 (Denso)
    Fuel level sending unit.. $80 (OEM on eBay)
    Secondary filter housing... $35 (OEM on eBay)
    Gasket/O-ring... $13
    I'm looking at $260 give or take to rebuild the fuel pump assembly.

    Strange though. When i input 23300-50120 for the secondary filter housing, Toyota parts show it does not fit a 2005 with the 4.7L.
