    UPDATE:

    After moving and storing the bike, I've finally had time to diagnose and figure my issue out. I had a bad ground inside the 90* connector that sits on top of the fuel pump assembly. Not sure how it even happened bc the piece is covered in potting compound. I'll and load photos at some point.

    Any issues running with this pump?

    This was the connector on the top of the fuel pump assembly that was bad (broken ground connection within) on my 2014.

    I couldn't find a reasonably priced new EBR fuel pump assembly so I ended up using an 1125 fuel pump assembly after switching over the 1125's thermistor fuel level system for the 1190's float style. Bike is finally (after a year of being down) back up and running.

    For those interested. This is the Buell 1125 fuel pump assembly:

    Verses the EBR 1190 fuel pump assembly (with aftermarket float):

    I may be out of touch, but I haven't seen anyone suggest using the 1125 fuel pump in our bikes. They are certainly cheaper (a quick search yields a $255 price) and the o-rings are also available for less than $6.00 for a pair. I saw in your post in another thread that the Carter pump number even appears to be the same.

    I'm curious as to whether the thermistor fuel level system would also work on our bikes. I wonder why the change from Buell to EBR on that?

    I believe the pumps between the 1125 and 1190 to be the same since both have the 61522 etched on them like I mentioned in my other threads post, but didn't want to chance it throwing everything back together and the bike not running right. My issue was wiring within the 1190 fuel assembly, so I was able to use my stock 1190 pump in the 1125 assembly. Also Carter, whom makes the pumps, is very quiet regarding the specs on their propriety pumps. You're correct in pricing though, 1125 replacements can be had for MUCH cheaper than 1190 pumps. I bought the 1125 assembly I retrofitted into my EBR for $55 plus shipping off ebay! Now thats compared to used 1190 assemblies going for $250ish and being quoted $400 for a new unit from a last remaining dealer with one.

    As for the fuel light systems, I thought about how both work off resistance and researched a little about them. The thermistor style reads temp of the fuel. Then combined with ambient air temp readings by I imagine other sensors and the ECM then determines low fuel when no fuel is on the sensor to "cool" it. From what I read, the float style is more reliable over the thermistor style. Even then, I don't believe the 1190 is equipped with the other items needed to use the thermistor. So in sum, while the 1190s float isn't exactly ideal, I believe it's at least more reliable over the 1125s system.
