  Hey guys. I replaced my old gas gauge with a brand new one and have a problem. The car has half a tank of gas in it, but the gauge reads 3 notches below empty! It isn't even in the gauge register zone. The sender is a brand-new AC  NOS  piece and I know it's good. I know that sometimes if these gas gauges are dropped that the needle can be jostled out of position because only a tiny pin on the back of the needle holds the needle on. Would it be feasible to take the gauge back out, move the neeedle to half a tank, and expect it to read correctly from there? Or would power from the sender have to be going to the gauge when the needle is repositioned? Or is this even possible? I hate to think I just dropped $200 on a new gas gauge that isn't worth a hoot. Thanks!

Gauge should read full with sender wire disconnected and empty with sender wire hooked to ground. If this is not so check power to gauge or suspect gauge itself.

FYI when my 69's sender wire was disconnected, the gauge read beyond E/F marks (with ground-wire connected).
