AKSGKGQ Fuel Gas Tank Grommet & Shut Off Valve
This valve kit targets generators and lawn equipment that use a 33/64″ hole. It fits Coleman Powermate 4200 and 5000 generators and MTD/Cad lawn equipment, including mowers and tillers. The kit combines a shut-off valve with a rubber grommet for a secure seal. Best for owners replacing a worn fuel shutoff or upgrading to a combined valve and bushing solution.
Best for: users replacing multiple machine parts across Coleman, MTD, and Cad/Cad equipment requiring a compatible 33/64″ mounting hole. This kit is a practical choice for mixed-tool garages with several engine models.
Limitations: verify exact part numbers (e.g., 951-0171, 735-0149) match your machine; installation may require basic gasket seating to prevent leaks.
Savior Generator Petcock Fuel Gas Tank Switch Shut Off Valve
The Savior petcock is a 16mm x 1.5mm threaded valve with a 22mm hex nut, designed for Predator, Champion, Generac, and Honda-style generators. It includes a shutoff switch with a 90-degree operation and built-in filtration mesh to trap debris before reaching the carburetor. Best for: users with Chinese-made or widely used commercial generator models who need a widely compatible replacement valve.
Limitation: ensure the exact model and thread match before purchase; some models may require additional adapters for perfect fit.
YGQ Generator Fuel Petcock Shut Off Valve
The YGQ valve is built for broad compatibility and specifies M10 x 1.25mm threading, targeting many Champion, Generac, and Firman models. The design emphasizes a robust zinc alloy valve body and a 90-degree shutoff for quick fuel control. Best for: users with a wide range of portable generators that use M10 x 1.25mm fittings.
Limitation: verify thread size on the specific generator valve inlet; mismatched threads prevent proper sealing and may require adapters.
CARBBIA 2 Pack 90 Degree Valve With Grommet
The CARBBIA kit provides two 90-degree fuel shut-off valves with grommets designed for 192980GS/208961 Kohler variants and various portable generators from Generac, Troy-Bilt, and Rotary. Best for: users who want a compact 90-degree solution for multiple Kohler and Generac-based systems or portable generators with similar mounting holes. Avoid if your model requires a different hole size.
Limitation: this pack targets specific Kohler and Generac lines; confirm the compatibility with your exact model before buying in bulk.
Qeykizy Professional Generator Petcock Valve
The Qeykizy valve is designed for a broad range of 5.5-16HP generators (190F to 420CC engines) and supports many Predator, Generac, Honda, and other brands. Its M16 x 1.5mm thread and 22mm hex nut facilitate installation, while the 90-degree valve enables quick shutoff. Best for: users with mid-size generators seeking a versatile, widely compatible shut-off valve with solid build quality.
Limitation: compatibility varies by model; double-check the engine family and thread spec to avoid misfit.
Buying Guide
Key considerations when selecting a generator gas tank valve
- Thread size and mounting hole: Verify thread pitch (M10 x 1.25mm, M16 x 1.5mm) and hole size (33/64″ vs 1/2″) to ensure a snug fit.
- Valve orientation: A 90-degree valve typically offers easier routing and serviceability in tight spaces; choose this if space is constrained.
- Grommet compatibility: Some kits include a grommet; confirm material quality and hole fit for sealing against fuel leaks.
- Range of compatibility: If you own equipment from multiple brands, prefer valves explicitly listing broad compatibility (Predator, Generac, Honda, Kohler, Troy-Bilt, etc.).
- Material and durability: Zinc alloy bodies resist corrosion and support long-term use in fuel environments.
- Maintenance considerations: Look for built-in filtration or mesh features to protect carburetors from debris.
Practical comparison takeaways
- Best for broad compatibility: Qeykizy or Savior, depending on your engine family.
- Best for hole-size specific installations: AKSGKGQ and CARBBIA kits target 33/64″ mounting holes.
- Best value for dual-pack needs: CARBBIA 2-pack provides two valves, useful for multi-equipment setups.
Frequently Asked Questions
- What is a fuel petcock valve used for in generators?
It acts as a shut-off mechanism to control fuel flow from the tank to the carburetor, enabling easier maintenance and fuel management.
- How do I know which thread size I need?
Check your generator’s fuel valve inlet size; common sizes include M10 x 1.25mm and M16 x 1.5mm. If in doubt, measure or consult the manufacturer’s parts list.
- Are 90-degree valves better than straight valves?
90-degree valves can simplify routing in tight spaces and reduce kinks in fuel lines; choose based on your mounting area and hose layout.
- Can I replace a valve with any brand?
Compatibility depends on thread size, mounting hole, and fuel line fittings. Always verify model compatibility before ordering.
- Do these valves require reglazing or special tools to install?
Basic hand tools are typically enough; ensure proper sealing with fresh grommets and correct torque to avoid leaks.
- Is a built-in filter important?
Yes. A mesh screen inside the valve helps trap debris and protect the carburetor from clogging, extending equipment life.
