Frequently Asked Questions
Q: Will this carburetor fit my Onan?
A: This carburetor is designed for Various Onan P126G, P128G, P220G with the Onan P-Series & B-Series engine. Please check the compatibility table above and verify your specific model year and engine code before ordering. If your vehicle falls outside these specifications, it may not fit. Contact our support team with your VIN for confirmation.
Q: How difficult is the installation?
A: Installation difficulty is moderate. Most DIY mechanics can complete this in 1-2 hours with basic hand tools (socket set, screwdrivers). You'll need to remove the carburetor assembly to access the boots. We recommend replacing all four boots at once for even sealing. Apply a light coat of silicone spray to the inner surface of the boots for easier carburetor installation.
Q: How does this compare to the OEM part?
A: This iFJF carburetor is manufactured to meet or exceed OEM specifications in materials, tolerances, and performance. You're getting OEM-equivalent quality at a fraction of the dealership price. All iFJF products undergo multi-point QC inspection before shipping.
Q: What warranty comes with this product?
A: All iFJF products include a 1-year limited warranty against manufacturing defects. If you experience any issues with fitment or function, contact our support team with your order number for a replacement or refund.
Q: How fast is shipping?
A: Orders ship from our US warehouse within 1-2 business days. Standard delivery takes 3-7 business days depending on your location. Expedited shipping options are available at checkout.
Q: How do I know if my intake boots need replacement?
A: Common signs include: rough idle, hanging RPMs, backfiring through the carbs, vacuum leaks (hissing sound), cracked or hardened rubber, and difficulty tuning the carburetors. If your boots are original and over 10 years old, they're almost certainly due for replacement. Rubber hardens and cracks over time, causing air leaks that make proper carburetor tuning impossible.
Q: Should I replace anything else while I'm in there?
A: Since you'll have the carburetors removed, we recommend also inspecting/replacing: carburetor gaskets, fuel lines, vacuum hoses, and air filter. If your carburetors haven't been cleaned/synced recently, this is the perfect time. Doing everything at once saves significant labor down the road.
