Customer Question

I have an Onan 5.5HGJAB-1038D. I'm replacing the carb, but I can't seem to find a match. I find some that say they're compatible but the fuel filter application looks different. The current carb I have has the threaded type with female end on carb. If they no longer sell the carb and I have to switch, which carb should I buy and what matching fuel filter should I get?
Also If I have to switch anything else I should be aware of, such as governor linkage changes and such.

Thank you for allowing me to assist you, my name is Joe and I will be happy to assist you with your concern today.

I'm showing this as a replacement:

The fuel filter only matters in the aspect it provides the same filtration min as the factory and does not restrict, it is not as important as the pump and carb but does play a role.

I'm showing a replacement fuel filter of Part Number:48-2048 for the hgjab engines. Even if a line was changed and not threaded it would simply take a threaded to barb connector to use it.

Thank you!
- Joe
