Frequently Asked Questions
Listings may describe 249127 as a repair kit (seals/internal wear parts) or as the fluid section / pump lower. Check your sprayer’s parts manual and the product contents to ensure you’re ordering the configuration you need.
Match your exact model/series (e.g., 390 Series A, Nova 390, Duron 390, FinishPro 390) and compare the pump lower part number in the official Graco parts manual. If your 390 is a different revision, the pump lower may be different.
Loss of prime, low pressure, pulsation, fluid leaks from the lower, or visible packing wear typically indicate the pump lower/packings need service or replacement.
Basic hand tools are typically sufficient. Follow Graco torque specs and assembly order. A soft-jaw vise and packing lube can help ensure correct installation without damaging parts.
Newer 390 revisions may use different pump lowers or repair kits. If your model isn’t explicitly listed above, check the latest Graco parts manual by serial number or contact support to confirm compatibility.
