Default Pipe thread on Andair filter-pump leak

Im using the Andair pump and Andair filter. They mate together with a pipe thread.
I have tightened it as much as I think is safe without damaging it but it continues to leak at this joint. Any idea how I might get it to seal.
Thank you
Gary

Pipe threads need a sealant. What are you using?
Do not use teflon tape. Do not use RTV.
Many like Permatex (#2, iirc), there are others.

I like Locktite 567 with PTFE in a tube. Amazon has it.

I have been researching this as well as I am working on the fuel tanks and need to seal some pipe threads as well. My research on the forums has revealed most use permatex #2 and Loctite 567. The loctite has had the most "rave" reviews.

permatex #2, PTFE sealant, Loctite 567, NOT teflon Tape. All of those have good results. YMMV. Used PTFE for years.

You know, I have a question about this filter...I have the Andair pump/filter combo as well.

What's the point of the safety wire on the filter? If it's screwed into the pump at one end, and a fuel line (from the fuel selector valve, in my case) is screwed on the other, how would the filter case *ever* unscrew itself?

Granted, I don't have it handy, so I'm going by memory, but still...?
