This is a UGP aftermarket replacement filter and should not be described as a genuine Cummins Onan OEM part. Verify compatibility using the generator’s complete model number, serial number, specification letter, and original filter number before ordering.
During installation, remove the old gasket, clean the mounting surface, and lightly lubricate the new gasket with clean engine oil. An appropriate filter wrench may be required for removal. Follow the tightening instructions in the operator’s manual and check for leaks after running the generator.
