    you'll be able to tell from my pics if yours is modded or not. another 2010-only pump clue is that what appears to be reg. has a large metal finger-style clip holding it in place.

    do as you please but considering the fact that this part # appears to be gone now, i would work with what you have...do a full rebuild...carefully check all wiring again including the main wiring feed to the pump harness itself.....and hope that solves your problem.

    Thanks Barrett, the pump you showed above is the exact pump that I have in my bike so I guess I have the unique to 2010 XB fuel pump that I can no longer buy. Figures...

    So a couple of questions for you:

    1. Will the P0130.5AA work as a substitute even with the built in regulator? I ask because more than a few sites that sell these pumps including SPHD list that part number as a fit for a 2010 XB

    2. If the pump I have does not have the built in regulator then what is that part that looks like a reg and held in with the metal clip? (just curious on that one)

    Definitely rebuild it, Barrett can set you up with a rebuild kit ( I think ).

    What concerns me is what looks to be a dent in the middle picture on the upper part of the shiny metal piece ?

    That dent is on the fuel filter so I don't think it would be a deal breaker. Not sure if I did that getting it out (most likely) or if it was like that from a previous install. I am the 4th owner of this bike and I have very little maintenance history to work with. I'm kind of just winging it with that and even if I knew more I doubt it would change much in how I approach this repair. It truly does suck that I bought the only bike with a one year only fuel pump. Makes me wonder what other surprises I have in store.

    Barrett, is it true that you sell some sort of repair kit for these pumps?

    Gord: i don't have a definitive answer for you regarding the regulator-appearing component other than, i suspect, it's a one-way valve of sorts to retain line pressure as the ECM cycles the pump on and off. of the 60 or so pumps that i've rebuilt to date only 2 have been 2010-only models, and no mystic trickery involved to successfully rebuild one. as previously mentioned the main difference between yours and all prior year pumps is that increased amount of output pressure, and that the pressure is ECM controlled via the fuel-rail factory sensor. other than that, rest of the components pretty much standard issue.
    ON THESE XB PUMPS AS FOLLOWS:
    the 2003 pump readily identifiable as it has a pair of tall tubes to hold the components together and rubber 90 degree pressure line.
    the 2004-2009 pumps the same BUT the pump harness plug different. 2004-2007 same plug.....2008-2009 same plug but 2008-2009 plug will not fit the earlier style main wiring harness. however, the plugs can easily be swapped so that the 2008-2009 pump will plug into the earlier style main wiring harness.

    a 2010-only pump CAN be installed on an earlier model XB if you fashion a proper regulator to fit so that the pressure is internally regulated and not ECM regulated. however, i know of no way to fit an earlier style pump to a 2010 model XB. i know of nobody who has successfully attempted it, nor have i.

    FUEL FLOW DIRECTION VIA COMPONENTRY: fuel enters the pump via filter sock...into and thru motor...thru pressure hose to regulator....thru regulator to high-pressure filter....out said filter thru outlet port to main fuel feed line. on all models prior to 2010, the back-side of the regulator has a no-pressure hose attached to it that terminates at base of the pump body. this line carries "bleed-off" fuel from the regulator. it is directed via the hose to the base of the pump body to avoid noise being generated inside the tank/frame when fuel level gets low, and to avoid cavitation. the 2010 pump has no such feature.

    and YES...i carry full rebuild kits for all year pumps. i mentioned a few days ago to you what i would do if i were in your situation, and hope for the best.
