Lawn Mower Fuel Filters, Pumps & Accessories

What is included in this collection? Mow Town USA offers replacement fuel filters, fuel pumps, shutoff valves, fuel caps, tank bushings, vents, hose clamps and fuel-line service parts for lawn mowers, zero-turn mowers, string trimmers, generators and other small-engine equipment.

Shop by the original equipment part number, engine brand, equipment model, fuel-line diameter and component type. Before ordering, compare the inlet and outlet size, mounting style, hose routing, venting requirements and overall dimensions with the original part.

How to Choose the Correct Fuel-System Part

1. Identify the component you need

• Fuel filters: help capture debris before fuel reaches the carburetor or fuel system.
• Fuel pumps: move fuel from the tank to the carburetor or engine on compatible equipment.
• Shutoff valves: allow fuel flow to be stopped during storage, service or transport.
• Fuel caps and vents: seal the tank while allowing the correct venting for the equipment design.
• Tank bushings and grommets: seal fuel-line or fitting connections at compatible fuel tanks.
• Clamps and service kits: secure fuel line and replace related wear components together.

2. Match the fuel-line diameter

Check the existing hose and fittings before ordering. Common small-engine fuel-line sizes include 1/8, 3/16 and 1/4 inch, but the required size depends on the equipment. A filter, valve or fitting with the wrong connection size can leak, restrict flow or fail to stay secured.

3. Compare the OEM or replacement part number

The most reliable starting point is the original part number from the equipment manual, engine parts diagram or existing component. Cross-reference numbers can help identify compatible replacement parts, but all physical specifications should still be compared.

4. Verify fuel-flow direction

Some inline filters and pumps are directional. Look for an arrow or inlet-and-outlet markings on the original component and replacement listing. Install the part in the direction specified by the manufacturer.

5. Check pump type and port arrangement

Small-engine fuel pumps may use pulse, vacuum or mechanical operation depending on the engine. Compare the number and position of ports, mounting holes, body shape and hose connections. Do not select a pump only because it looks similar.

6. Confirm cap and vent requirements

Fuel caps may be vented, non-vented or use a separate vent assembly. Match the thread, neck size, sealing surface and venting design required by the equipment. Incorrect venting can interfere with fuel flow or allow leakage.

Frequently Asked Questions

How do I know which fuel filter fits my mower?

Match the original part number, fuel-line diameter, filter shape, inlet and outlet size, and any equipment or engine application listed in the product description.

Are small-engine fuel filters universal?

No. Some inline filters fit several applications, but connection size, flow capacity, direction and equipment requirements can differ.

What does a 1/4-inch fuel filter measurement mean?

It generally refers to the fuel-line connection size. Confirm that both the hose and filter fittings match the equipment before installation.

Can I replace a fuel pump with one that looks similar?

Appearance alone is not enough. Match the operating type, port configuration, mounting pattern, hose size and replacement part number.

What is the purpose of a fuel shutoff valve?

A shutoff valve allows the fuel supply to be closed on compatible equipment. It can be useful during servicing, storage or transportation when installed and operated according to the equipment manufacturer’s instructions.

Do I need a vented fuel cap?

Use the cap or venting arrangement specified for the equipment. Some systems vent through the cap, while others use a separate tank vent.

When should fuel-line clamps and bushings be replaced?

Replace components that are cracked, hardened, loose, leaking or otherwise damaged. Inspect the related hose and tank connection at the same time.

How can I reduce the chance of ordering the wrong part?

Provide the equipment brand, model number, engine model, original part number, fuel-line size and clear measurements. Compare each specification rather than relying only on the product image.
