Tab vs Screw-in Filter Screen (Flame Arrestor)

[v8fordman]

I am currently in the process of cleaning out a late ‘30/‘31 gas tank with Rust 911. It is sealed and full of solution, upside down, so I can’t see the filler opening. In short, how will I determine if my tank takes a tab or screw in filter screen? Are the screens interchangeable? Maybe it will be obvious when I can see the opening, but just thought I would get a head start. Anyone have pictures?

if there are threads in the neck of the tank — screw in one
if there are slits it has the tab type

Are the threaded style gas tank flame-arrestor filler screens being produced? Major suppliers seem to only have the tabbed version.

1. It will be obvious which you need.
2. You can drop the tab type in the tank filler opening meant for the screw in screen and it will just hang there.
3. Don't bother. They are a pain in the neck. You don't need it.

Seriously.

So they are not necessary as a flame arresting precaution then? Got it.
thanks

They were designed and used for a reason. They do make it slower to refill your gas tank.

Most modern cars don't include a screen.
