Hello all,

I installed a 70900070A speedo unit the other day on my 05 heritage softail (carbureted) and the fuel gauge isn't working. Do i have to d/c the old unit?

Any thoughts would be helpful,

Rob

 

I have the same problem with my 06 carb bike and I called harley and they said that it will not work on carb bikes. I cursed them for not putting that note in their fitment guide before I spent $300. Still an awesome gauge though.

 

My 06 fuel injected plugged up and worked fine gears tach and fuel

 

I put one on my 08 last week...easiest gauge replacement I have ever sone. 10 minute job tops, all works fine. Maybe check with dealer you got it from, there are some exceptions to what works on what bikes, but I didn't disconnect the tank gauge, it still although the speedo gas gauge is much more accurate. Good luck with yours!
