Mike Morrin makes a good point. As in his unit the fuel inlet flow
surrounds the outside of the pleated filter passing through to the inside
and to the carbs. The pre 1968 AC fuel filters were designed to use the
filter gauze ( a thin round fine mesh screen with a hole in the center which
accomodates the inlet pipe) and not the paper cartridge. When used as
designed the filtering process is the same as Mike described, i.e. fuel into
the bowl, fuel out through the filter gauze, sediment falling into the bowl.
I may be wrong about this, but I believe people started using the paper
filters on these older units when the filter gauzes became impossible to
obtain; they eventually would deteriorate. A few years ago I couldn’t get
the filter gauze for my 150 and replaced it with the paper filter. A short
time later I had the same experience as Mike Burnett. Desecting the filter
I found it completely plugged on the inside. Replacing the gause with the
paper filter reverses the original design intent causing the debris to be
trapped inside the filter instead of falling away to the bottom of the bowl.
Another point, after empting the glass bowl you may find that the fuel will
not pump back into the bowl–due to air lock. With the pump running
carefully loosen the bowl just enough to allow the air to bleed out and fuel
to enter. Then stop the pump tighten the bowl and recheck for leaks. On an
old Franklin I noticed there was an air bleed screw on the filter housing
just for this purpose.
BTW, is this list slowly being taken over by “Mikes”?

I second everything you have to say and as you well know I speak from experience
with the %$#@#&* fuel filters and what they can do to your E at the least
convient time, like between Phoenix and Tucson.

Well, Well, Well!!!
When I received the new filter from Terry’s, guess what? It didn’t look like the
“correct” filter that I’d had in there previously. IT HAS A HOLE CLEAN THROUGH THE
MIDDLE so that fuel will go from the outside in!!!
I think my Argentinian friends have an appropriate expression for this occasion,
which is best not repeated here, but has to do with canine ancestries…
Thanks to all who have commented. Now to see what evil lurks at the pickup screen
in the tank…

After several hours, I discover upon removal of the filter body to the workbench so I
can see what’s going on, that the old filter was longer by a bit, with a short spring
on the bottom that kept it pinned to the filter body. The new, shorter one fits snugly
over a lip with no spring required. I can now see how the new one, with the hole clean
through, will filter the gasoline properly from the outside in. The old one was
obviously a worthless forgery. In my haste to get the car running after the
restoration process 10 years ago, I fell for it. H’mmm, just wondering what other
witchery I’ve got next to… And, to tell the truth, I’m not positive I replaced this
particular piece upon restoration.
So for all you folks out there who might restore one of these things from the ground up
and not knowing so before hand, there’s two filter elements that will fit in the
glass-bowled filter body and ‘work’. The longer one with a spring on the bottom and no
hole at the base will not work properly. But this is not obvious till you go through
what I just did…

I check my fuel filter once in a while, and am amazed that it never gets dirty. well,
well, well. It must be getting dirty from the inside out.

“What I Don’t Know About Jags” would be a provocative title. Put me down for the first copy
of the first edition, autographed. Also put me on the list of those to whom you intend to
lend the tilter when you are done with it.
