John Deere L110 Fuel Pump Test

If you own a John Deere L110 lawn tractor, chances are you’ll eventually have to test the fuel pump to see if it’s working properly. Here’s how to do it: First, make sure that the fuel shut-off valve is in the “on” position.

Next, remove the gas cap and unscrew the fuel line from the carburetor. Place a funnel into the carburetor and pour about a cup of gasoline into it. Now, turn the key to the “on” position (do not start the engine) and let the fuel pump run for a few seconds.

You should hear it humming or see gasoline flowing out of the fuel line. If not, then your fuel pump needs to be replaced.


If you’re having fuel pump problems with your John Deere L110 lawn tractor, you’re not alone. Many owners have reported issues with the fuel pump, and it’s a common problem with this model. There are a few things that can cause fuel pump problems on the L110, and most of them are fairly easy to fix.

One of the most common causes is a dirty or clogged fuel filter. If your filter is dirty, it won’t allow enough fuel to flow through to the engine, and the engine will run lean and eventually stall. Another common cause of fuel pump problems on the L110 is a faulty carburetor float needle.

If the needle is stuck in the “open” position, it will allow too much fuel to enter the carburetor bowl and flood the engine. This can be easily fixed by replacing the float needle with a new one. Finally, another potential cause of fuel pump problems on the L110 is a bad voltage regulator.

If your tractor’s voltage regulator is failing, it could be sending too much or too little voltage to the fuel pump, causing it to work improperly. Replacing the voltage regulator should fix this problem.
