While troubleshooting my fuel guage I ran across a good couple of articles I thought I would share.

I know this is for 63 to 67 but it has some good info that pertains to c3's.
Here is a nice website for more info

Jon, what was wrong with your fuel gauge?
On my last tripwhen I filled up the gauge would not go to full stopped at like 3/4. I thought maybe the float was stuck. But then I did that bonzi run at the Glen and that for sure should have un stuck it. It will go down from this point. I'm baffeled?
Thanks,

I'm pretty sure the coil in the guage went bad. My old guage would not go up past 1/4 tank when the thank was full. I first tested the printed circuit for the guage cluster for breaks, corrosion and any loose connections. Everything checked out good. I bench tested the guage with a known good sending unit. I took the pink wire from the sending unit to the guage then put 12vdc + and - to the guage. I then moved the float arm on the sending unit to full and down to empty and the guage would not go past 1/4 full going up but would go to E when the arm was at the bottom. When I bought the new guage I did the same test and the new guage checked out perfectly. I had guage problems back in May but it turned out to be the tank bladder had bulged out and was keeping my sender float from going down past half a tank. Needless to say I replaced the tank and that fixed the problem.
