Sending unit fix?

I have a spare on the bench. I'll try it and let you know if this work's. I'm sick of screwing with mine too. :brickwall:
 
Mine shows full, then at about ten miles shows 3/4, then shortly after that it drops to 1/4 and stays there no matter how much is in the tank even if its empty. It might be worth a try. Thanks for the info.
 
Thanks for the info. Hopefully someday else will try it and post some pics........... and their opinion if it works!

:hack:
 
I tried it on the old sending unit I have from my old tank. Did not seem to be any different ohm readings than just grounding it to the tube. Both places read the same, 11 ohms full and 68 ohms empty. These number's are close to what my new one was too but that does not tell you where the level in the tank is when the sending unit and the guage on the dash read different. I hooked up my new sender to the car before I put it in the tank and it was not even close to the gas guage on the dash. I run it through it's full motion several times with no luck on getting it close. And further more , the old sender was not close either and it is the original. :huh: How does one know how much fuel is in the tank when this is the case ? Beat's me. I dumped 10 gal. of gas in the car today and it barely read's 1/8 th of a tank on the gauge.... I know, :blah: :blah: :blah:
 
Mine's a driver, and always will be. I'm seriously considering putting in an aftermarket fuel gauge. I've been driving around for a month on E, and I have no freaking clue on how much gas I really have.

What I was doing is to have some idea of what you mpg is. In my case it's around 10, so I would write down the mileage when I put in gas so I would then know that I could go around 150 miles and still have about a quarter of a tank left, (these cars have a 19 gallon tank,) so I know it's time to get more gas! But of course, if your odometer dosen't work then you are SOL!!!!

I tried that, but that's way too much math for my simple brain!! :crazy: Actually, I'd usually forget to write down the mileage, or loose the receipt somewhere along the way.

I still thing it all has to do with the angle of the rod the float is on and how far we need to bent it to get it adjusted right . My 2 cents

When I put my new sending unit in last year I tried bending the arm. Definitely did not fix the issue. On a full tank it'd go to 1/2 tank, then drop within 30 miles or so to an empty reading and stay there.
 
I read somewhere that the problem may not be in the sending unit but in the voltage supply to the dash gauge itself.

It can but you would see problems with other gauges I would think :popcorn:

That's a bad sending unit. I got as close to the potentiometer as possible, there is about a one inch section that I bent until the float is almost above the sock at empty and its pretty close. I have five gallons at a quarter and full goes a little above full on the gauge

that is when you see the gauges peg, then drop of, then return to normal. I had that in my Charger with the Rally cluster, but I've never had it happen in any of the road runners.
