I suspect this may be one of those "which is better - chocolate or vanilla" questions but here goes. I found a neat little AC fuel filter with a glass bowl and wondered if it makes any difference weather the bowl points up or down? The built-in ones on the fuel pumps have the bowl on the top, but the metal cover on the stand-alone filter has a logo on it which you couldn't see if the glass points up.
Whaddaya think folks?

In the far gone past these were called a "Sediment Bowl" with the glass on the bottom so crud could settle there.

ah, an interesting question, indeed; I have personally worked with engines that were engineered to operate with both "above" and "below" locations of the glass-bowl filter/reservoir. Despite the notion that gravity favors the "sediment-bowl" theory, the top mounted reservoir-bowl has been found to operate very well.

Great info! I was actually planning to put it right next to, and upstream of, the fuel pump down on the right side of the block.

Mike -
I'd put it down next to the fuel pump, too. My worry with putting it where the Accessories manual shows would be that I'd go to clean the bowl out while the exhaust manifolds are still hot, spill some gas and start a fire.
Maybe someone else can chime in as to whether or not that is a realistic worry. I have no experience with trying it.

I have 2 Carter W-1 carbs on a Fenton manifold so it will be a bit crowded near the stock location. Seems like a good idea to keep crud out of the fuel pump too.

Don't try this at home kids, but I'm believe you need a open flame or spark to ignite the fuel, not just heat. Though I would be very careful.
I do know that my '51 F-sorry-D Flathead has the sediment bowl attached to the manual pump on top of the intake manifold at the rear of the engine. Another place that I wouldn't want to spill fuel on a hot engine.

The vapors and a spark will get you every time. Vapors alone are not extremel hazardous or we would have trouble filling the tank in the first place. But I have learned that most any thing can happen at just about any time.

the question that was asked was whether it makes any difference if the glass bowl is mounted "Up" or "Down". Your comment was very interesting, but did Not answer the man's question. The answer is No, it does not matter whether the glass bowl is "up' or "down".

you can actually cause an explosion and fire by "actually putting out a cigarette in gasoline", if you are a wise-guy and make the mistake of assuming that the invisible vapor that sits on top of liquid gasoline cannot cause any harm.

fuzzy,
Welcome to CT. I am sure they can work both ways and some engines may be engineered differently. The engine in question was designed in the 40s or 50s (or earlier). The sediment bowls, be it on cars or more commonly tractors of this era, were certainly designed to be installed with the bowl down. When most any debris (or even water) hits the bowl, it falls to the bottom allowing fuel to move through the bowl (and screen) to the carburetor. Turned upside down, everything would rest on the screen or just get pushed through if the screen were removed (not uncommon). Plus, which one do you want to remove. The one that spills gas as you take it off, or the one that can feasibly hold the fuel as you remove it.
you can actually cause an explosion and fire by "actually putting out a cigarette in gasoline", if you are a wise-guy and make the mistake of assuming that the invisible vapor that sits on top of liquid gasoline cannot cause any harm.

Not to throw fuel on the fire (pun intended), but the fuel pumps with a glass bowl and filter have the bowl on top, like this:
So, as you said, it can be either way. And I have no idea what would be "best."

kensluys,
I've got an old one from my 52' or more likely my parts 51', I will have to investigate. If there is a filter element top to bottom that the fuel has to move through, then the glass bowl is just a see-through filter housing and not acting as a sediment bowl. None of the old tractors (different I know) had more than a mesh screen filter at the top. Of course, most tractors operated with gravity fuel flow vs. a pump. I will look at the one I have and post back what I find.

In the down position. If you need to clean out the bowl do it after the engine cools down then you won't have to worry about the gas spilling out onto the exhaust manifold and people won't make fun of you for installing it upside down .

I would definately put the glass down. otherwise ediment gets trapped on the other part out of view.

as far as the fuel filter or "sediment bowl" goes i have always seen them mounted glass down.
but i do have a question on glass fuel pumps.
i have 5 or 6 or them and some are with the glass bowl down and some are with the galss bowl on top.
is it just a difference between o.e.m and aftermarket pumps?
or were they different from year to year?

No, it is definitely Not a difference between OEM and aftermarket fuel pumps. The design is set and constructed to the engineering designs of the engine manufacturer, just like a million other parts. The Fact that a lot of forum participants cannot personally visualize the glass bowl being "on the top" is irrelevant.Cars and trucks have been constructed with BOTH configurations, and that's that. We all have "opinions" about this or that. Opinions have no effect whatsoever on the actual facts of how a vehicle is actually built.Notions and whims and maybe's are very entertaining conversation. But facts are facts. as far as the fuel filter or "sediment bowl" goes i have always seen them mounted glass down.

Some Factories went with the bowl "UP", and I will go with THAT. Each Application called for a Specific Design, it was carried out, whether "UP"or "DOWN". The Vehicles speak for themselves,"Public Opinion" doesn't enter into it. What you are doing here is entertaining a popularity contest as to whether opinion goes one way or another, on whether "Gravity" helps sediment fall down or up, and that's nonsense. BOTH Styles were Made. They BOTH WORK. THE GLASS BOWL DOES NOT NEED TO BE "DOWN".
Factory did it for a reason, bowl down. I would do the same.

This is a 49 to 54 Chevy site and the 1951 accessory manual shows the bowl being installed, bowl down. Enough said on that subject.
You're a new poster here, take a deep breath and relax .... your "in your face" comments are not going to impress the troops here.
