In this blog post, we’ll go over some common symptoms of a faulty fuel sending unit and what you can do to fix it.
If your Jeep Wrangler is having issues with the fuel sending unit, there are a few things that could be causing the problem. The most common issue is a faulty float, which can cause the gauge to read inaccurately or not work at all.
