1970 road runner Fuel Gauge issues

[Lucky LAr]

Can’t get fuel gauge to read full when the tank is full of gas

I have to sending units, one brand new the other looks original, when I hook them up out of the tank the sending units & the gauge in the car work perfect

But when I put them back in the tank they will only go to a little under ¾ when the tank is full

Has anybody had the same issue, and is there a fix

Thanks larry

This is a common problem and there are many threads here on the subject. Just put "fuel gauge" in the search and you'll get several results on the subject.

not sure of this is gonna help but make sure you have LOTS of grounds on the car/motor/dash/gas tank.
old mopars love lots of good grounds.
