This is an authentic replacement part sourced from the original parts manufacturer and is used in various models of Troy-Built, Yardman and MTD Lawn Tractors. The purpose of the fuel filter is to filter out any contaminants and impurities before they can enter the carburetor, causing it to become clogged. Replacing the filter regularly helps keep the engine and carburetor running at peak performance. The filter is an individually sold part.

Received parts in timely manner. Fixed tractor and back to mowing. My son is very happy. He did not like push mowing. Maybe, I should have waited till the end of the summer to fix the tractor.

Screwdriver, Pliers, Socket set, Wrench Set, Nutdriver, Carb cleaner (dip and spray), small nylon scrub brush.
1) Removed cowl from mower for access to carburetor. Removed air cleaner.
2) Removed and disassembled carburetor paying attention to how throttle and governor linkages are hooked up. (A picture taken with phone is a handy reference for re-assembly.)
3) Cleaned carburetor as much as possible with spray carb cleaner, brush and shop air.
4) Placed metal parts of carb in dip basket, soaked in gallon of carb cleaner overnight to remove residue.
5) Reassembled carburetor using parts from repair kit and bowl replacement kit.

7) Cleaned gas tank, replaced old fuel line and fuel filter. Installed in-line fuel shut off valve.
8) Installed air cleaner assembly, replaced old air filter & pre-filter.

Time
15-30 minutes

1. Remove air filter cover and air filter.
2. Be sure fuel tank is empty. (I turn it sideways below the steering column so the outlet is below the fuel filter.)
3. Remove fuel filter from fuel line and disconnect fuel line from carburetor.
4. Remove ground wire and disconnect wiring from bottom of carburetor float bowl.
5. Use socket or nut driver to remove 2 nuts holding carburetor on engine.
6. Gently slide carb off bolts and carefully remove choke and throttle cables (requires some jiggling around).
7. Reverse steps to install carburetor.
8. Install new fuel filter in fuel line (be sure flow arrow is correct).

Used gaskets, fuel filter & heat shield as part of a carburetor freshen up on a MTD Yardman with Kohler 15 HP engine. Parts fit great, did have to trim the "ears" off the heat shield with a dremel tool to make the carburetor linkage clear...but that only took a minute & the old tractor fired right up & is running great!
I'll definitely use e-replacement parts again!

Be careful not to damage the small plastic insert from the throttle linkage on the carburetor and the other end of the throttle arm as these parts do not come with the kit.
To remove a carburetor and put a new one on is a easy job, will need a mm socket set. The engine on the lawn tractor started up first time with no problems.
