Essential Gear: Protecting Your Investment and Ensuring Basic Functionality

Before you even think about power boosts, make sure you've got the foundational elements covered. These accessories are about preservation, safety, and reliable operation.

Shielding Your Asset: Generator Covers & Storage Solutions

Your Predator 3500 works hard, often in less-than-ideal conditions. Protect it from dust, dirt, rain, and UV rays with a good cover.

Heavy-Duty Weatherproof Cover: Look for covers made from durable, water-resistant material like marine-grade polyester. Features like elastic hems, drawstrings, and buckle straps ensure a snug fit that won't blow off in a gust of wind. Some even have access panels for running the generator while covered in light rain, although always ensure proper ventilation.
Why it matters: Prevents rust, protects electronic components, and keeps your generator looking new. It's a small investment that pays off big in the long run.
Storage Considerations: When not in use, store your generator in a dry, covered area. A sturdy moving dolly or a dedicated generator storage shed can make access and placement easier.

Fueling Smart: Management and Efficiency

Fuel is the lifeblood of your generator. Managing it effectively impacts performance, safety, and longevity.

High-Quality Fuel Stabilizer: If your generator (and its fuel tank) sits unused for more than a month, fuel can degrade, leading to carburetor gumming and starting issues. A good fuel stabilizer prevents this. Add it to fresh gasoline, even if you plan to use it relatively soon, especially for long-term storage.
Pro Tip: Run the generator for a few minutes after adding stabilizer to ensure it circulates throughout the fuel system.
Safe Fuel Cans: Invest in approved, high-quality gasoline cans. Modern EPA-compliant cans can be tricky to use, so practice beforehand. Always store fuel in a cool, well-ventilated area, away from ignition sources.
Large-Capacity Fuel Funnel with Filter: A funnel helps prevent spills, and one with a built-in filter screen can catch debris before it enters your fuel tank, protecting your carburetor.
Extended Run Fuel Tanks (External): While the Predator 3500 boasts impressive run times, for truly long periods of continuous operation (e.g., multi-day power outages or extended RV trips), an external fuel tank can be a game-changer. These tanks connect to your generator's fuel cap or vent line, siphoning fuel automatically.
Considerations: Ensure compatibility, secure placement, and use only with proper venting. This can dramatically extend run time without frequent refills.

Grounding & Security: Peace of Mind

Safety and security are paramount.

Grounding Kit: Proper grounding protects against electrical shock. While many applications, especially with modern RVs or small tools, don't strictly require generator grounding if the generator is not connected to a building's electrical system, it's always a good practice, especially in damp conditions or if you're using it to power a home via a transfer switch. A basic kit includes a grounding rod and heavy-gauge wire. Always consult your generator manual and local electrical codes.
Anti-Theft Cable Lock: A portable generator is a valuable asset and an easy target. A heavy-duty steel cable lock, secured around the generator's frame and to an immovable object (like a trailer hitch or tree), can deter opportunistic thieves. Look for hardened steel and pick-resistant locks.

Maintenance Essentials: Keeping it Prime

Just like your car, your generator needs regular TLC.

Spare Spark Plug: A fouled or damaged spark plug is a common cause of hard starting or poor performance. Having a spare on hand (and knowing how to replace it) can save a lot of headaches.
Engine Oil & Oil Change Funnel: Use the recommended oil type (typically 10W-30 or SAE 30, depending on temperature). An oil change funnel specifically designed for generators makes draining and refilling less messy. Consider synthetic oil for better cold-weather performance and extended change intervals.
Air Filter: A clean air filter is vital for engine performance and longevity. Keep a spare and check/clean your filter regularly, especially in dusty environments.

These kits usually involve a module connected to the generator's electrical system, allowing wireless ignition.
Wireless Monitoring Systems: Some accessories allow you to monitor fuel levels, run time, and even power output via a smartphone app. This eliminates guesswork and ensures you're aware of your generator's status without having to physically check it.

Propane/Natural Gas Conversion Kits: Fuel Flexibility

This is perhaps the most impactful upgrade for many users, fundamentally changing how your generator consumes fuel. A dual-fuel or tri-fuel conversion allows your Predator 3500 to run on propane (LP) or even natural gas (NG), in addition to gasoline.

Benefits:
Cleaner Burning: Propane and natural gas burn cleaner than gasoline, resulting in less carbon buildup, reduced emissions, and potentially longer engine life.
Extended Storage Life: Propane and natural gas don't degrade like gasoline, eliminating carburetor gumming issues and the need for fuel stabilizers. Tanks can be stored indefinitely.
Easier Storage & Availability: Propane is readily available in portable tanks (like those for BBQs) and can be easily stored. Natural gas offers an unlimited supply if you have a connection.
Safer Fuel: Propane leaks dissipate quickly (though still flammable), unlike spilled gasoline which creates hazardous fumes.
Considerations:
Power Output Reduction: Generators typically experience a slight (5-15%) power output reduction when running on propane or natural gas compared to gasoline.
Cost: Conversion kits vary in price, and installation can be complex.
Installation: While some kits are designed for DIY installation, others may require professional expertise, especially for safe natural gas connections. Incorrect installation can be dangerous and void your warranty.
Warranty Impact: Modifying your generator, especially its fuel system, can potentially void the manufacturer's warranty. Research this carefully before proceeding.
Types of Kits:
Dual Fuel: Gasoline and Propane.
Tri-Fuel: Gasoline, Propane, and Natural Gas.
Most kits involve a new carburetor or an adapter that allows the alternative fuel to enter the engine.

Exhaust Extensions & Deflectors: Safety and Sound

Managing exhaust fumes is critical for safety and can also influence noise.

Exhaust Extension Pipes: These direct the exhaust fumes away from your operating area, reducing noise and, more importantly, minimizing the risk of carbon monoxide (CO) exposure. They connect to the generator's muffler and extend the exhaust pipe.
Crucial Safety Note: Even with an extension, never run a generator in an enclosed space, garage, or near windows/vents. Always use outdoors with plenty of ventilation.
Muffler Deflectors: These direct the sound of the exhaust upwards or to the side, potentially reducing the perceived noise level in a specific direction. While not a massive reduction, every bit helps.

RV Ready Adapters & Power Cords: Seamless Integration

For RVers, specific accessories ensure your Predator 3500 integrates flawlessly with your rig.

RV-Specific Power Cords: Standard 30A (TT-30P) or 50A (14-50P) RV plugs with sufficient gauge wire and length are essential. Ensure the cord can handle the full output of your generator.
L5-30P to TT-30R Adapter: The Predator 3500 typically has an L5-30R twist-lock outlet. If your RV uses a standard 30A RV plug (TT-30P), you'll need this adapter to connect.
Surge Protectors: Generators, like shore power, can sometimes have voltage fluctuations. A high-quality RV surge protector or electrical management system (EMS) protects your sensitive RV electronics from spikes, low voltage, and other power anomalies. This is highly recommended for any RV owner.

Critical Safety Additions: Non-Negotiable Protection

Some accessories aren't about convenience or power, but about life and limb. These are non-negotiable.

Carbon Monoxide (CO) Detectors

Standalone, Battery-Powered CO Detectors: These should be placed in any area where exhaust fumes could potentially accumulate (e.g., inside your RV, tent, or home if using the generator for backup via a transfer switch, though the generator itself should always be outdoors). Carbon monoxide is odorless, colorless, and deadly. Ensure your detectors have fresh batteries and are tested regularly.

Fire Extinguisher

ABC-Rated Fire Extinguisher: Keep one nearby whenever your generator is in operation or being refueled. Gasoline is highly flammable, and electrical faults can occur. A small investment for a significant safety measure.

Making Smart Choices: What to Consider Before You Buy

With so many options, how do you decide what's right for you? A few key factors should guide your purchasing decisions.

Your Primary Use Case

Are you a full-time RVer, a weekend camper, a homeowner prepping for emergencies, or a contractor on a job site? Your specific needs will dictate which accessories offer the most value.
