I have an 87 Savage and i had my tank painted recently. I also took off the petcock and then used KBS coatings tank sealant to recoart the inside as there was a little rust I could see and we noticed a lot of rust in the filter attached to the petcock. Anyway we popped the filer off easily and cleaned it out. Now I'm ready to put it all back together and I remembered how easy the little filter came off. My question is, does that filter just fit down in the holes left for it or do i need to use some sort of attaching glue or epoxy?  When i took it off there seemed to be a bit of crusty white stuff around it but i wasn't sure if that was from it just sitting there being old or oxidation or something or if it was remants of some adhesive that is supposed to keep it attached.
 Anyone know?

Thanks ahead! I'm ready to get back out there next week if I can get it all working smoothly again!

I'm pretty sure the filter clamps between the petcock and tank when bolted up.

I'm also pretty sure ol' burny misread your post.
