Paid Up Posted June 10, 2019 Report Share Posted June 10, 2019 My question for someone about a fuel sending unit in all the boats I have owned I have never had one go bad. Mine gauge all of a sudden blinks empty all the time even with a full tank. I check the connections today and all look good. A buddy told me it is probably bad so I am planning on replacing. Question - do they just go bad? One day it worked fine and then next day it just blinks empty? Quote Link to comment Share on other sites More sharing options...
BlueMojito Posted June 10, 2019 Report Share Posted June 10, 2019 Check the connections for corrosion before you replace anything. If you have an ohmmeter, you can test the resistance of the sending unit directly. There's lots of threads on the web and some helpful YouTube videos as well. As always, when working around your fuel tank, be extra careful to avoid sparks or shorting out power to ground! It's a great opportunity to leave your battery powered tools in the box.

DAME TU LONCHE Posted June 12, 2019 Report Share Posted June 12, 2019 I had a similar issue with my gas level showing non consistent levels. Bought a new one for my 2200v 2002. Got the Moeller Reed, hoping to install this week. Moeller 035761-10 Reed Switch Fuel Sending Unit - 9" Tank Depth Quote Link to comment Share on other sites More sharing options...
SCFD rtrd. Posted June 12, 2019 Report Share Posted June 12, 2019 Fuel sending units are very sensitive to corrosion and loose connections. First thing I'd would do is (with batteries off) remove the positive wire and clean it, then remove the ground wire and clean. Replace and see if it makes a difference. Also remove and clean the connections on the back of the gauge. Quote Link to comment Share on other sites More sharing options...
