Hipa 6-PCS Fuel Tank Grommet Bushing
The Hipa set targets users needing reliable, leak-proof grommets for 13 mm tank holes. The kit’s I.D. is 3/8 inch with an O.D. of 1-1/16 inch and a height of 5/8 inch, aligning with common Toro, Craftsman, and Troy-Bilt models. Best for general maintenance on portable generators, lawn equipment, and pressure washers. Choose this if you want a cost-effective pack to cover multiple machines. Caution: verify hole size and compatibility before purchase.
Why this is a strong pick
Bulk pack ensures replacements without downtime. The grommets are designed to fit 13 mm holes, a common size across brands. It’s well-suited for homeowners who service several pieces of equipment or operate rental fleets.
Potential limitation
Not all models use the same exact O.D.; confirm the 1-1/16 inch outer diameter matches your tank cutout to avoid a loose seal.
Fuel Gas Tank Grommet & Shut Off Valve Set
This kit combines a gas tank grommet with a shut-off valve, designed for 33/64″ holes. It supports Coleman Powermate 4200/5000 generators, MTD/Cub Cadet mowers, snow blowers, and tillers. It’s a practical option when you need both a replacement valve and a grommet in one order. Best for users who service multiple legacy models. Limitation: verify the exact part numbers (e.g., 951-0171, 735-0149) to ensure compatibility with your equipment.
Why this is a strong pick
Having both the grommet and shut-off valve in one kit reduces downtime and mis-matched parts. The kit references multiple compatibility notes, useful for mixed fleets.
Potential limitation
Some models may require a slightly different valve thread or fuel line size. Always measure the hole and line diameter before ordering.
10 Pack Fuel Tank Bushing Grommet 33/64
This bulk pack targets budget-conscious buyers needing multiple replacements. It lists a 3/8 inch I.D. with a 11/16 inch O.D. and a 5/8 inch height, designed for 13 mm tank holes. Best for seasonal maintenance on generators, pressure washers, and riding or push mowers. Choose this if you want a ready supply for ongoing maintenance. Caution: ensure you don’t overfill or expose the grommet to petroleum solvents that could degrade rubber over time.
Why this is a strong pick
The bulk configuration is ideal for shops or households with several gas-powered tools. The stated dimensions match common hole sizes, aiding quick swaps.
Potential limitation
Material composition isn’t specified beyond “rubber” on the listing. If you operate in extreme conditions, check chemical compatibility with your fuel and cleaners.
6 Pack Generator Fuel Tank Grommet 46-6560 104047
Designed for MTD, Troy-Bilt, Toro, and similar brands, this six-pack includes grommets compatible with 13 mm holes and matches part numbers 46-6560 and 104047. Best for mid-range generators and zero-turn mowers. It’s a practical choice for replace-as-needed maintenance programs. Limitation: verify model and part number matches to avoid fit issues with newer equipment.
Why this is a strong pick
The pairing of two common part numbers in one listing helps ensure compatibility across a family of machines, reducing guesswork during ordering.
Potential limitation
Availability may vary; confirm the exact hole size and O.D. before purchasing to prevent leaks or poor seals.
Fuel Gas Tank Grommet And Shut Off Valve
This option targets a broad set of brands including Generac, Coleman, Craftsman, and McCulloch. It features a 33/64″ hole compatibility and includes a shut-off valve, suitable for service on multiple equipment lines. Best for mixed fleets with legacy and newer tools. Limitation: ensure the 1/4″ ID fuel line compatibility with your existing hose connections.
Why this is a strong pick
A versatile kit helps technicians consolidate parts across brands, saving time when maintenance requires both a grommet and a valve.
Potential limitation
Some machines may require different valve or hose configurations; double-check hose ID and inlet/outlet layouts before ordering.
Buying Guide: Key Considerations For Generator Fuel Tank Grommets
What hole size is correct? The common size discussed here is 33/64″ (13 mm). Confirm your tank hole diameter prior to buying to ensure a snug seal and leak prevention.
Is a shut-off valve necessary? If you want immediate shut-off capability and easier fuel management, choose kits that include a valve. If not, go with a simple grommet replacement.
Material and durability matter. Rubber grommets resist vibrations and weather exposure, but check for fuel compatibility and resistance to common solvents used with generators and lawn equipment.
Model compatibility is critical. Listings often reference multiple brands and part numbers. Always cross-check your equipment model, year, and original part references (for example 735-0149, 46-6560, 104047) to avoid mismatches.
Bulk versus single packs. For households with several tools, bulk packs save time and reduce the chance of running out of spares. For a single device, a focused replacement may be more cost-effective.
Practical buying tips
- Measure the hole and the O.D. of the grommet to ensure a tight fit.
- Check whether the kit includes a shut-off valve or only a grommet.
- Prefer listings that specify compatible brands and part numbers.
- Inspect the rubber compound and its resistance to gasoline and ethanol blends typical in your area.
FAQ: Quick Answers For Generators And Grommets

A: No. Compatibility with the hole size, O.D., and fuel exposure matters. Always match part numbers when possible.
Q: How do I know if a kit fits my Craftsman or Troy-Bilt mower?
A: Verify the listed compatible models or cross-reference the manufacturer’s part numbers (e.g., 735-0149, 46-6560) with your mower’s manual or parts diagram.
Q: Are these grommets suitable for high-velocity pressure washers?
A: They can be, provided the hole size and material resist fuel and exposure; verify the exact product’s stated applications.
