I’m looking at a boat this weekend that has a fuel gauge that doesn’t work? I have never had to replace one before. I was wondering if anyone may know or a estimated guess on how much having one replaced is?
Check the sending unit first!
What boatpoor said^^^^include checking the gauge also !!!
If i remember correctly</font id=“size2”></font id=“size4”></font id=“red”> back side of gauge has 3 terminals pos , neg , and S , { S should be from sender on tank}, with jumper wire touch S terminal to Neg terminal , gauge should go to full , if no , check voltage with volt meter, between pos and neg on gauge, should read 12volt dc, assuming voltage is correct then “bad gauge” , if gauge goes to full when jumper is applied go to sending unit at tank , should be a pink wire and a black neg wire connected to sending unit , pink wire goes directly to S on back of gauge , jumper pink to black neg , gauge should go to full , if no , then probability wiring or connections between sender and gauge is bad. , if yes then sender itself is most likely bad…Bad gauge or sender imo would not be a game changer if I liked the boat… good luck
You could always just replace sending unit and the actual fuel gauge on the dash for around $50 total. That way you know they are both new and hopefully won’t have to worry about either one for a while. Both are fairly easy to replace. Replaced sending unit on mine and took about 20 minutes to change. Turned out the gauge is bad too so that’s next up for replacement.
Whatever you do, start with the most expensive part first and replace down the line! When you get it all replaced, you’ll find out it was a bad ground wire connection:wink:
Easy’s being a smart azz:smiley:
but he’s mostly right!!![:0][:0][:0]
Thanks gail. Ask me how I know the advice I gave Tan:face_with_head_bandage:
I would guess ;; Been there a few times before…
Your fuel gauge is basically an ohm meter. Your sending unit is basically a rheostat (variable resistor). I doubt the gauge is bad. Probably a connection issue or the sending unit in the tank is bad. If it has some age on it you’d do better to replace it. I’d start with cleaning up the connections and then the sending unit. Pretty inexpensive and you’ll use it the life of the boat.
An “investment” in your future.

That’s y’all for the help. I will make sure I start with the most expensive!!!#128077;#127997;

I have found over the years you cant beat a stick! Put in the tank to the bottom and see how much is wet when you pull it out!
If it’s a newer boat, a stick won’t get past all the EPA,BS:face_with_head_bandage:
