How To Fix ATV Fuel Gauge Issues

Have you ever gone out riding just for your ATV to run out of gas unexpectedly? You’ve checked your gauge over and over again, but it keeps on reading that you have half a tank. Regardless of what your fuel gauge says, sometimes there are a lot of issues that can leave you stranded out in the middle of the trail. This is when you need to learn how to fix an ATV fuel gauge before you’re out there all alone.

There are a few different reasons that your fuel gauge isn’t reading properly, so you’ll need to start by diagnosing the problem. If you’ve done any mechanical fixes before, you’ll understand that the diagnosis is the hardest part while the fix is usually pretty simple. Here, we’ll go over a couple of things to try before simply replacing the entire gauge.

Poor Connection between Gauge and Sensor

The first thing to check is the connection between the gauge and the sensor. This is a spot that will often wear thin or come loose and create a weak or completely broken connection. The wire plug on top of the fuel pump unit is most easily accessible by removing the passenger seat.

Here, there are many wires running from the fuel tank to other parts of the machine. Simply check all of the connections by checking that all of the wire pins are securely fastened in place. Push each one in firmly and it’s entirely possible you’ll find some of them that will move. Now you can check to see if your gauge is back in working order.

Gauge Float Misaligned

If the connections aren’t the problem, you may be experiencing an issue with the gauge float. Sometimes these will get stuck and struggle to move, so they just need a nudge. In order to do this, you’ll need to disconnect the plugs on the fuel pump and remove the black screw ring holding the pump down. This will open up the fuel tank so be highly cautious of any open flames or sparks.

With this disconnected, you can move the gauge float and check its mobility. If it’s back to working properly, replace everything as it was and test it out. If not, you’ll need to replace most everything.

Replace It All

Unfortunately, it can come to the point where you need to replace everything. You’ll need a new fuel pump, float, and anything under the pump lid. The parts are easily found online for a decent price, but it’s more work for you. The good news is that you can use this opportunity to upgrade and get a new fuel pump that works more efficiently than the last.

If you’re hesitant on any of these fixes, it’s highly recommended that you seek the help of a professional. Messing with the fuel pump can quickly go wrong with disastrous results. Approach this task with caution and care.
