Question fuel/air leak

What is the best way to stop air from "leaking" into the fuel warmer. I have a new o-ring for the top of it but did not realize that I was leaking at the connector.

I have a 1991 3/4ton 4x4.

Thanks

What about removing the heater? I would probably need a shorter stud for the filter, would anyone know how short and were they can be gotten? Thanks

I went to my local cummins dealer and they wanted $25 for the stud and $15 for shipping!!? What a crock.

What about using a silicone to "plug" the port until I can locate a short stud at a decent price?

Just pick up a universal filter head and bypass the factory setup all together then.
