Thread Sealer on Fuel Filter of Cummins Onan Generator
Most of the pictures that I see of a new fuel filter, show a red substance on the threads where it screws into the fuel pump. The one that I purchased, even though it was an OEM filter, didn't have any sealer on the threads. It did have a removable plastic cover to protect the threads until installation.
Is a sealer needed, or is it a compression seal?
Thanks for the help!
