Fuel sending unit replace

Don't toss your old one, If you don't like the way the fuel gauge works with a replacement you may want to consider having it rebuilt. also watch the fine print, some senders or gauges require specific gauges or senders and/or instrument voltage regulators (IVR) My experience is that aftermarket ones don't have the correct non linear sending unit resistance wiring, causing the fuel gauge to read incorrectly. In my case it read ~1/4 to 1/2 till it was empty and full till it was 1/2 or there abouts. There are many treads about this issue.
