I've had the fuel pump/sender combo installed in my car for a few years now, but it's only in the last week that the car has actually been driving and had a full tank of gas. However, I've noticed two issues:
- With a full tank of gas (it spilled out of the filler a bit), it reads mostly full, but not completely full. Like, 15/16th full. You can see a decent gap between the the full mark and the need.
- The low fuel light never comes on. I found this out when I went for a test drive and the car cut out. Took me about 10 minutes of tinkering before I realized my fuel pressure gauge read zero. I just thought the fuel gauge was reading low, but not actually empty (if it wasn't on empty, it was really really close, but the light wasn't on, so I still had some fuel, right?).
Now, the low fuel light bulb might just be burned out. I haven't gotten around to taking the fuel pump access cover off again to test it yet (re: it's cold out). Before, the fuel light was the only thing that worked reliably, as the old sender had was rather... non-linear.
So, is there some way to calibrate or adjust the fuel sender? And what are the chances that the sender isn't triggering the light vs it being burned out? I really should just answer that last one myself by testing the bulb, though.
Thanks!
