My low fuel indicator light has been coming on prematurely for a while. It's intermittent, but a little annoying. Seems like the only BW'ers here with that problem ended up replacing the entire fuel pump (under warranty). Well, I'm long since out of warranty (51,000 miles) and I wonder if anyone has just replaced the sensor? I haven't looked in the shop manual yet for exactly how it's attached to the fuel pump. While the fuel pump's out, I also want to prevent the wires from shorting out (as has happened to BW'er Adrian 8 at Bryce Canyon).  Thanks for any info. --Doc | ||

I think they use the same type of sensor as my old X1. They are odd. No moving parts at all. It's a metallic cylinder that has one wire coming out. It looks like a condenser from points only smaller. It has some odd arrangement inside with an incandescent bulb and a thermistor. You have to get the pump unit out but I'll wager that it's replaceable. My X1 light stopped working at about 8000 miles and tried three times t get it fixed under warranty. I finally gave up and stopped caring  Just out of curiosity, did you check your fuel pump wiring? 50,000 is long enough for corrosion + vibes to take a toll. | ||

Sensor is about $15 plus 2 o-rings needed to reinstall the pump. My light started coming on intermittently about 20k ago, gradually got to staying on all the time. I haven't changed it yet. I was concerned (briefly) about chafed wires causing it, but after all this time I think it's just the sensor. I have always used the trip meter as a fuel gauge on all my bikes, so it isn't a big deal to me. Eventually I'll replace the sensor. | ||

Paul56 Posted on Thursday, August 14, 2008 Sensor is about $15 plus Have a part number on that sensor? I remember someone saying it's part of the fuel pump, and not serviced separately... | ||

My low fuel sensor started to go bad around 11,000 miles, and completely failed (on all the time) around 14,000 miles. The dealer replaced just the sensor. I repaired the fuel pump chaffing wire issue around 27,000 miles and got a close look at the sensor. It is very easy to replace, at least once you have the fuel pump out. Here are the parts needed: P0789.KA - Sensor, low fuel - $14.00 P0121.02A8 - O-ring, fuel pump - $6.15 (x2) P1203.3AB - Drain plug w/ o-ring - $4.40 The book calls for a new drain plug, which may not be absolutely necessary, but spending the $4 might be better than having a fuel leak under pressure and having to drain the frame again.  While you're in there...you might want to do a preventative fix on the likely chaffing wires.   | ||

What is that thing you secured the wires with and what is it made of? Is your son fully recovered and back in the saddle? | ||

Hey EG: I used two very small plastic cable ties, which acts as a spacer...keeping the wires from contacting the aluminum wire bracket, and also prevents any vibration of the wires. It seems to have solved my fuel pump issues from 4,000 miles ago (prior to homecoming trip). And thanks for asking about Sean, he is doing fine and thinks that the collar bone is all healed, but I am encouraging him to still take it easy for a while. As far as the saddle...I'm still waiting on a few parts to get the Blast back up and running. You saw what the bike looked like after doing a full summer-sault, you might be shocked (like me) to learn that it will only take about $180 to get her back up and running (the major parts purchased used). Of course that doesn't include cosmetic pieces, but I am just going back to the old black plastic set for now. | ||

Glad to hear it. Time to get him a ULY. | ||

Thanks to all; exactly what I was looking for. |
