The fuel filter in a Craftsman lawn mower can be found inside or attached to the fuel line, or inside the gas tank. The mower's engine may run roughly or not at all if the fuel filter is dirty or clogged. Fuel filters are essential for preventing debris from reaching the carburettor and disrupting the air-fuel mixture, which can lead to poor engine performance. Craftsman lawn mowers with fuel filters usually have them on the pickup hose in the fuel tank.

What You'll Learn
Craftsman lawn mower fuel filter location
The exact location of a fuel filter on a Craftsman lawn mower varies from one machine to the next. However, it is generally inside or attached to the fuel line, or inside the gas tank. Craftsman lawn mower fuel filters can be replaceable or non-replaceable.
The replaceable kind is either a small plastic canister with pleated material inside, or a thin, straw-like tube-style device with a fine mesh at one end. The canister style connects to one end of the fuel line, while the straw style slides inside the fuel line where it connects to the gas tank.
The non-replaceable kind is a metal mesh at the bottom of the gas tank where it empties into the fuel line.
To replace a canister-style filter, locate the fuel line and use pliers to release the spring clips holding the line to the gas tank spigot and filter. Pull the fuel line off the spigot and remove the filter. Check the transparent plastic casing to see if there is debris inside or if it is severely discoloured. If so, you will need to replace it. There is no way to conveniently clean canister-style filters, but they are cheap and easy to replace.
For tube-style filters, once you have located the fuel line, use pliers to release the spring clips holding the line to the gas tank spigot and filter. Pull the fuel line off the spigot and remove the filter. Check the meshed end for dirt or debris. If there is any, rinse it out carefully with water until it is clear, or buy and install a new filter. Once you have a new filter or have cleaned the old one, installation should only take a few minutes.

How to replace a Craftsman lawn mower fuel filter
Not all Craftsman lawn mowers have fuel filters. Older models, in particular, may not have them. For those that do, the fuel filter is generally found inside or attached to the fuel line, or inside the gas tank.
To replace a Craftsman lawn mower fuel filter, first, park your mower in a flat area, like inside your garage. Drain all the gas from the tank with a siphon, or simply run the mower dry outside. Disconnect the wire from the spark plug so that the engine doesn't start while you're working.
Next, locate the fuel line. With pliers, release the spring clips holding the line to the gas tank spigot and filter. Pull the fuel line off the spigot and remove the filter. Examine the filter to see if it is clogged or dirty. If it is a canister-style filter, look through the transparent plastic casing and examine the pleated material inside. If it is a tube-style filter, look closely at the meshed end. If you see debris or severe discolouration, you will need a new filter.
Once you have your new filter, push the ends of the fuel line segments onto the spigots of the filter and use pliers to replace the spring clips. Be sure to install the canister-style filter in the correct direction, usually indicated by an arrow on the casing pointing in the direction of fuel flow. For tube-style filters, simply pop the new one into place, ensuring it is oriented the same way as the old one.
Finally, reconnect the spark plug wire and lower the tractor hood.
