ERAYAK High Altitude Jet Replacement Kit for 2400P Inverter Generator (3000–12000 ft)

High-Altitude Performance Kit Keep Your Gasoline Engine Tuned for Thin-Air Operation At higher elevation, a standard carburetor setup can run too rich, causing harder starts, higher fuel consumption, spark plug fouling, and reduced performance. This high-altitude jet replacement kit helps match the carburetor fuel delivery to mountain conditions when the correct kit is selected for your engine and elevation. Designed for gasoline engine carburetor high-altitude adjustment. Use above 3000 ft elevation when the correct kit is required. Includes the service parts shown in the instruction sheet. Installation should be completed by a qualified individual. Why High Altitude Needs a Different Jet As elevation increases, air density drops. The instruction sheet states that the standard carburetor air-fuel mixture can become too rich at high altitudes, which may reduce performance and increase fuel consumption. A matched high-altitude main jet helps correct the mixture for the selected operating range. Cleaner Tune Adjusted Air-Fuel Balance Replaces the standard main jet with a high-altitude main jet to better suit thinner air conditions. Mountain Use For Elevation Above 3000 ft The included instructions identify high-altitude operation starting above 3000 ft; 0-3000 ft does not require a high-altitude jet. Protected Setup Keep the Original Jet If the engine is later moved below 3000 ft, the original main jet should be reinstalled. Choose by Operating Elevation Select the correct high-altitude jet according to the elevation where the engine will be used. The kit packaging shows metric altitude ranges; the table below converts those ranges into feet for easier comparison with the instruction sheet. Fuel Metric Label on Jet Bag Approx. Feet Equivalent Kit Guidance Gasoline 0-914 m 0-3000 ft High-altitude jet not required according to the instruction sheet. Gasoline 1000-2000 m 3281-6562 ft Use the jet marked for the 1000-2000 m range when the engine operates in this elevation band. Gasoline 2000-3000 m 6562-9843 ft Use the jet marked for the 2000-3000 m range when the engine operates in this elevation band. Gasoline 2438-3658 m 8000-12000 ft Use the correct high-altitude jet specified for this range; performance may still decrease above 8000 ft. Altitude conversion: 1000 m is about 3281 ft, 2000 m is about 6562 ft, and 3000 m is about 9843 ft. Confirm the engine model and the correct kit part number before installation. What the Kit Supports Main Jet High-Altitude Main Jet Replaces the existing carburetor main jet with the correct high-altitude jet for the selected operating range. Seal Bowl Gasket The instruction sheet lists a bowl gasket for reassembly after the carburetor bowl is removed. Washer Washer / Seal Use the new washer or seal provided with the kit to help complete a proper repair. Guide Operation Instruction The included instruction sheet shows the carburetor bowl, emulsion tube, altitude main jet, and reassembly steps. Installation & Safety Checklist This kit is a carburetor service part. Installation requires fuel-system handling and replacement of the carburetor main jet, so the work should be completed by a qualified individual following the official operation instruction. Before Service Shut the engine off and allow it to cool completely before starting installation. Clamp the fuel hose or drain gasoline from the fuel tank so fuel cannot flow to the carburetor. Work in a well-ventilated area away from open flame, sparks, and other ignition sources. During Reassembly Install the high-altitude main jet and check the jet number against the correct altitude range. Use the new bowl gasket and washer/seal provided with the kit during reassembly. Do not cross-thread or overtighten the carburetor bowl bolt. After installation: Wipe up any spilled gasoline and allow remaining fuel to evaporate before starting the engine. Keep the original main jet, because it should be reinstalled if the engine is moved back below 3000 ft. Best For Generators Mountain Jobsite & Backup Use For gasoline generator engines operating above 3000 ft when the correct high-altitude kit is specified. Outdoor Power Gasoline Engine Equipment The instruction sheet references engine equipment such as generator sets, pressure washers, compressors, pumps, and tillers. Service Part Altitude-Specific Maintenance Use when moving equipment into sustained high-elevation operation and when the engine requires a corrected main jet. Generator Safety & Fuel Handling Reminder For generator use, follow all engine and generator safety instructions. Gasoline and exhaust can be dangerous when handled incorrectly. Never run indoors. Never run in a garage. Never run near open windows. Always operate outdoors with proper ventilation. Fire safety: Perform fuel-system work in a well-ventilated area away from ignition sources. If the engine is hot from use, shut it off and allow it to cool before proceeding. FAQ Do I need this kit below 3000 ft? No. The instruction sheet marks 0-3000 ft as not required for the high-altitude jet. Will this restore full engine power at very high elevation? Not always. The instruction sheet notes that above 8000 ft, the engine may experience decreased performance even with a high-altitude kit installed. Can I install it myself? The kit involves carburetor disassembly and fuel handling. The instruction sheet states that kits should be installed by a qualified individual. What happens if I move the engine back below 3000 ft? The original main jet should be reinstalled when the engine or equipment is moved to a location below 3000 ft. Keep the removed main jet for future use. Is this compatible with every generator? No. Match the kit to your engine model, fuel type, altitude range, and official kit part number before ordering or installation.
