the one I use or know of to come standard is NOT a fuel filter, no filter element inside that I'm aware of on a '69 440

The vapor separator is not a fuel filter.

Yes it is a filter, I use them as filters on both my cars.
I don't remember seeing a filter anywhere else on a 440 6 pack motor. I do remember seeing filters on a hemi, not sure about a hemi with a fuel pump mounted vapor separator?
Good question...

Its the only filter on my car. Wish there was room for another without cutting a line.

I snuck one in between the metal fuel line from the tank and fuel pump. Not that my car is perfect "OE" correct, but I am going for a stock appearance. It's hard to see underneath the engine.

My six pack set up has 3 of these in the carb bowls....

That's my point, I cant see the VS doing much to clean the fuel.
I was wondering if a filter before the pump hidden was a good idea - sounds like its not due to Vapor Lock potential.

A 'vapor separator' is not a 'fuel filter'...
I run the proper 'filter' in-line on a '71 B-body...
No 'Vapor' issues...

If memory serves me, 70, and 71 the VS was a 440/ Hemi thing, and did not get a separate filter. The service manual shows whats what, and which engine gets what.

Yes, the separator was designed to be a fuel filter also. However some of the repros had wrong size or no orifices. Does anyone know if they have the correct filter screen?
Here is the complete info from the '70 FSM in case anyone wants to read the explanation/description. It also says how to check for a plugged filter screen.

There are some bogus repro separators out there. I got one and could not figure out why the car would not start. Found that there was no orifice restriction in the return line and the fuel was going straight back to the tank and none going to the carbs
I cut it open to look inside. Surprise!! It was simply 3 tubes stuck into the can and there was no filter screen at all.

This is also a repro, but is correctly manufactured. Note markings on the can. The bogus one had no markings.

other end.
The return line was not orificed correctly. I soldered it closed and drilled a 0.040" hole- somewhat smaller than the factory size of approx. 0.060"

as far as being a filter, i ran just the vapor separator for years. i had the tops of the carbs off many times playing with jetting, and never once did i see any contamination in the bowls.
that doesn't mean there wasn't any, but i would assume if it wasn't doing it's job as a filter, at least to some degree, i would have seen some evidence of crud in the bowls.
