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?

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.

      I was up over the weekend to do cabin duties. I did get laker trout at cascade river Friday mornings it was 17 inches but made for great trout and eggs breakfast. Agree with maple bacon longjohn and Chet's doughnut. Also a must stop for me is trail center for lunch the 3 Cheese grilled cheese is amazing with a chocolate and peanut butter milkshake. Just look at this lunch

      I second Crooked Lake. Super clear water too. I kayaked in there recently and was amazed at how many sunnies are in there. First calm wind day I get I'm gonna get the yak in there and bring my flyrod.

      I woke up early Saturday tired and letting all the excuses in my head convince me to go back to bed. Cold front, high winds, clear skies. Screw it, I'm going anyway!   Glad I did. The wind was rough for yak fishing but I found them stacked right off a weedline and caught 7 bass within an hour on a stretch less than 75 yds.    Ended the day with the pig of a bass pictured and a nice Pike for dinner. Once the sun came out and warmed up the water I got action on the flats. That's where the big bass and pike came from. 8 bass total, one nice pike, a few short strikes on the flats. Wind sucked and what the heck is up with needing a sweater on the first weeked of Summer?!?! I'm not in the South anymore haha.

      Despite the occasional rain shower and relentless wind, had a great day on Fish Lake. Decent sized pan fish,  several out of slot, and 3 "eaters"  Walleyes were caught . The kids and wife all caught fish at a pace that kept me busy baiting, netting..(repeat) for a few hours. Not only was I fueling the addiction, but gaining points for future fishing trips. The only low point was when we went "Island exploring", someone was either in a hurry or just completely selfish and left their campsite garbage strewn to the point that it filled a 13 gal garbage bag.

      Nice catch Cliff. Were you rigging or bobbering?
