Genuine Cummins Onan Green Label fuel filter for the HGJBB (Spec A–B) QG 2500/2800 LP generator. Replace every 500 hours. Gasoline fuel only.
The Cummins Onan 149-2661 is the OEM-specified fuel filter for the HGJBB QG 2500/2800 LP generator (Spec A–B). It filters contaminants from the gasoline supply before it reaches the carburetor, protecting the fuel system from debris that causes clogging, lean running, and hard starting. Per the Green Label Parts Guide, replacement is every 500 hours of operation, or annually if fewer than 500 hours are accumulated.
Non-OEM "will-fit" fuel filters can be the correct shape but may use inadequate filter media or improper sealing materials that fail prematurely — causing fuel leaks or allowing unfiltered fuel into the carburetor. Genuine Green Label filters are tested and designed specifically for RV generator applications.
OEM-specified filter designed and tested for the HGJBB fuel system — correct media, correct fittings, correct sealing for reliable leak-free service
Replace every 500 hours of operation per the Cummins Green Label Parts maintenance schedule, or annually if the generator sees fewer than 500 hours per year
Designed for the HGJBB gasoline fuel system — the HGJBB does not have an LP fuel filter; this is the only fuel filter in the HGJBB service schedule
Filters debris and contaminants before they reach the carburetor — prevents clogging of small jets and passages that cause surging, lean running, and hard starting
The 149-2661 fits the HGJBB (Spec A–B) only. The brief's fitment description — QG 2800, QG 4000, Camp Power, MicroLite, MicroQuiet — is the column header from the Green Label Parts Guide, not this filter's compatibility. Each of those generator families uses its own fuel filter. Confirm your generator's complete model and spec number from the nameplate before ordering.
