fuel gauge not working

[andy j]

Just recently I have noticed that my fuel gauge on my lund just decided to not work anymore, any ideas on where I should start to find the problem? THanks

Andy, do a search for this subject, it has been covered numerous times.

You will have to troubleshoot if it's gauge or sending unit.

Valv,

I did a little looking around and have determined it is the sending unit, I took it off the tank and moved the float and it moved the gauge. Do I have to get a new sending unit? new float? If so where do I get one on short notice? anyway I can jimmy it myself? THanks

Check the ground. Sometimes they loosen or fowl and need to be tighted or replaced.

It is diffently the cork float, I took the float out of the tank and tried it in a bucket of water and it seemed to float fine but when I put it back into the gas tank which is full it doesn't seem to float. Can I get a replacement cork anywhere. Not sure it the cork is not a boyant as it once was. Not sure why its not working in the tank.

water is more dense than fuel. If the cork is fuel logged it will no longer float in fuel, but since water is more dense than the fuel logged cork will still float in water.

Airjer,

I was thinking that might what the problem was, Thanks, Do you think if I let the cork dry out then it will be good to go again, or should I try to find a cork replacement, If so any ideas on where to get a replacement?

[andy j]

Any of you know what I can use to reseal the cork after it drys to help prevent the gas from soaking back into the cork?

I don't know that I've ever seen a replacement float by itself... If I were you I'd try to find a replacement sender that has a float that is made of plastic. If it's close you could probably just take the float off the new sender and put it on the old sender... of course by at that point you could just replace the sender and be done with it.
