Just a light breeze Raymond, now you want long winded....
Unless you've got a new tank and new lines you have a 99% chance
that you'll be getting parts of the tank in your fuel system.
All of the original tanks that I've seem had some of that four
letter word, 'rust' in them and most had a bunch. The screen
beneath the glass bowl only takes out the bigger stuff a lot of
the smaller crud still gets thru and can cause problems at the
carburetor.
I feel that both the screen and accessory fuel filter are needed
to avoid problems. It bothered me that I was having to clean
the screen often, which was after the valves in the fuel pump
so I opted for an additional inline filter at the tank outlet.
Nothing gets thru to the pump now and I just change the inline
filter when I do a grease job.

accessory filter at the carb, which would assure that nothing
was getting to the carburetor. Besides, it looks like an
authentic dealer added accessory.
As far as vapor lock, I've never encountered it and
I've been driving my stock '50, 216 since '05 pretty
regularly without problems.
