GAV thread sealant

[stouchton]

Hi folks - looking for recommendations on sealing the GAV threads. Previous owner bottomed it out, and then used some type of pipe dope.

Tried Teflon tape, but it still weeps.

Searched the threads and found a recommendation for Permatex Aviation #3.

Is there something better someone has used? All my thread sealants do not work with gasoline

Thanks,

Scott
