#970 Fuel Pick up leaking at elbow

[TN Shelby Cobra]

Don't want to steel this thread but I have another question about the gas tank. Has anyone adjusted their float. My gas tank when full registers full . When empty it says 3/4 tank. I know years ago on my first car ( A 69 Mach 1) I just bent the rod a little and it register more like what was really in the tank. Can we do this on or Superformance cars? Thanks guys! Great site! , Mark

Rated at 20 ohms when full and 240 ohms on empty.
or:
NOTE: Sender has resistance values of 240 ohms at empty - 67 ohms at half scale - 20 ohms at full.(the higher the fuel level, the lower the resistance.)

Your wasting your time trying to get the sending unit to read correctly. I spent half the day trying to do so. I think the tanks are 16gal. So I just drained mine, put in exactly 4 gal. and made sure the gauge read 1/4. Adding another 4 gal. the needle reads close to 3/4. And then 4 more, it's past full mark, yet with room for 4 more. You might want yours adjusted where it would read 1/2 with 8 gal. Up to you, but don't waist a lot of time.

Now I know on mine anyway,, 1/4 means,,, hunt some gas SOON. It was embarrassing being the last car to leave local cruse night when car wouldn't start with gas needle just above E, and rear of car parked slightly down hill. That's what lead me to try and adjust mine, along with seeping gasket.

I'm sure others have tried, and maybe with better luck than I. Careful though bending sending unit arm, don't think it could take lots of bending before breaking. Best of luck.

Thanks! I will give it a try! Nothing worse then running out of gas!! Mark
