Hello folks. 2011 LR4. 173k miles ish.

The parking brake was randomly engaging, and is broken (won’t unlock), so I removed the 30 amp fuse under the hood to get it to stop until I could unplug the actuator.

I’ve since replaced the fuse after unplugging the actuator.

Now the fuel sending unit isn’t working. It’s showing empty. This started after removing the fuse. So I thought maybe they were connected somehow. I checked the fuel fuse under the hood as well, and replaced it for good measure.

Short of replacing the sending unit(s), is there something else I could check? Also, how do I know which of the two is bad?

Thanks for any advice.
