484285 Mower Fuel System Grommet, 486906 Fuel Tank Grommet Compatible with Scag SCZ48V 52V 61V 72V SCZII, Cheetah, Cheetah II & Freedom Z Zero-Turn Mower, Grommets Replacement for Scag Mower Parts

What It Is

This is a replacement fuel system grommet (part #484285) and fuel tank grommet (part #486906) designed to seal the connection between the fuel tank outlet and the fuel line on Scag zero-turn mowers. It prevents fuel leaks, air ingress, and debris contamination in the fuel system.

Fitment & Compatibility

Before buying, verify your Scag model and deck size. This grommet set fits:

• Scag SCZ48V, SCZ52V, SCZ61V, SCZ72V (all deck sizes)
• SCZII, Cheetah, Cheetah II, and Freedom Z series zero-turn mowers
• OEM cross-reference: Replaces Scag part #484285 (fuel system grommet) and #486906 (fuel tank grommet)

What to check:

• Confirm your mower uses two separate grommets (one at tank outlet, one at carburetor inlet). Some models use a single integrated grommet.
• Measure the inside diameter of your fuel line (typically 1/4" or 5/16") to ensure the grommet’s center hole matches.
• If your mower has a different fuel tank design (e.g., gravity-fed vs. pump-fed), compatibility may vary.

Key Things to Know

• Quality: Aftermarket part, not OEM. Users report good fit and sealing, but inspect rubber for any flashing or uneven edges before installation.
• Installation difficulty: Easy (10–15 minutes). You’ll need pliers to remove old grommets and possibly a small flathead screwdriver to seat the new one.
• Common gotchas: Old grommets can be brittle—remove carefully to avoid damaging the fuel tank or carburetor nipple. Apply a thin film of fuel-resistant grease to ease insertion. Do not overtighten any hose clamps; this can deform the grommet.
• Durability: Ethanol-resistant rubber, but prolonged exposure to E15 or higher ethanol blends may accelerate wear. Consider using ethanol-free fuel for longest life.

Should You Buy It

If you own a compatible Scag zero-turn mower and need to stop a fuel leak or replace dried-out, cracked grommets, this is a cost-effective, well-rated option. It’s a straightforward DIY fix that avoids a dealer trip. However, if your mower is under warranty or you prefer OEM parts for exact match, stick with Scag-branded grommets.
