My fuel gauge is operating at half function. Full is full, and half full is empty. I was hoping it was something simple like a bad ground, but reading here and at d source seems to indicate it's more likely to be an issue with the sender. The tank was dropped a few weeks back to replace the rear cross member, and I think the issue started then. This is a '94 NAS. Has anyone seen this particular issue before and any tips on getting it straightened out? Thanks all.
