Fuel Sending Unit #4051004 Tube Needs To Be Tweaked ?
It will be trial and error,
But here is a link that has the tsb about bending the tube. It doesn't apply directly to the A bodies but you will get the point
Dash wiring upgrades, Ammeter bypass, Dakota Digital guage cluster install...
Forgot to mention...
I tweeked mine a bit but I did not adjust it enough. When my car runs out of gas I still have 1 to 1.5 gallons in the tank.
Next time I pull the sender I will tweek it more.
