    I have been looking at the URD fuel-pump kit, mostly due to the filter; no plans for a S/C.
    My goal is to be exacting on maintenance, and do any upgrades aiding operational performance, to help this truck gain another 200k.
    Is there a reason I can't splice in a filter with the OEM setup?

    That is basically what the URD kit does. There is no S/C dependency. It adds an inline filter. Someone may have the part number but it can be sourced at the local parts stores and run that. The other part of the kit is the pump which is not required. Most of the S/C folks run the pump with filter then some run the external one as well.

    No need for one Toyota would have put one. You’ll get 500k without one.

    Stock has a filter within the pump housing. Adding a filter to the stock setup external from the tank does sort the problem of the stock filter getting clogged and causing the pump to work harder than necessary.

    The URD setups have aftermarket pumps that use a simple sock to get the big contaminants out that harm the pump, then push fuel through the finer external filter.

    This ^

    The OE filter is known to clog.
    There wouldn’t be much benefit to running the stock pump with filter and an external filter.
    And I don’t think leaving the OR filter off the OE pylon is a good idea.

    Like @nd4spdbh said.

    I guess the better question is: what is gained by adding a filter / new pump assembly to a fuel system holding proper pressure, and acting normally?

    Am I imagining a benefit of an additional, external, filter?

    TnShooter -
    I wouldn't remove the in-tank sock filter, perhaps replace it or the assembly entire.

    You won’t gain anything if the current filter is holding proper pressure.
    If you have no plans for serious power gains, I’d leave the current pump in until it gives you trouble.
    Which will likely be hesitation under load or a lean code.

    that's exactly how it is with passenger cars. They've done away with external filters and made it in the low pressure fuel pump, called a "sock"
    which clogs...

    vehicles with upgraded power levels can require better fuel pumps with more output to supply that demand.

    I don't fully understand why mfgs have gone this way with only a sock on the pump pickup and no external filter. But adding an external filter makes little sense unless you then remove the in tank sock. All things being equal I'd prefer to have an external filter and just a very rough sock on the pickup to prevent pump damage. But then my 120,000 mile 2009 is still running perfectly so I will not sweat this unless and until it becomes a problem.... which one would think could come from one bad batch of gas... or just a long accumulation of smaller stuff.

    When it comes to fuel filtration, toyota has used the prefilter sock + pump + fuel filter combo for ages. This has been used on the FJ62, FJ80, 100 series, pickup/ hilux, etc.

    I personally believe there is a benefit to using a filter after the initial prefilter aka fuel "sock". There is a good amount of junk that will make it past the initial sock attached to the pump. I see this nearly every time I replace a fuel filter on any 22RE, 3FE, 1FZ... Fuel that comes out of the used fuel filter looks like chocolate milk.

    Is a filter after the initial fuel sock "needed", no. Is there a benefit? Yes. Cleaner fuel will only help in the combustion process.
