Eliminating Sediment Bowl

Dellbertt · Apr 6, 2011

I've wasted enough time with leaking sediment bowls and going to eliminate them on my Farmalls - cub, sa, 300U(2). I use inline filters and there is absolutely no need for that sediment bowl being there.
I made one up using a street L and a shutoff. I also have one made coming out of the tank with a shut off and then turning 90 degrees. The second one uses a couple nipples making it lower than I would like but I like the shutoff at the tank. My local hardware carries an awsome collection but I can't find what I want in one piece.

Question: Does anyone know if they make a shutoff with a 90 degree bend in a single piece.
Maybe someone already makes a shutoff to eliminate the bowl.

Thanks,
Dell

I can't answer your question. I have 7 Farmalls, all with sediment bowls, ranging in age from new to who knows how old. None of them leak. If one does, and I can't stop it I just spend 20 something for a new one. Only my opinion and experience. And I know you didn't ask my opinion.

Sediment bowls shouldnt leak. Put a new gasket in and youll
be fine for another 50 years. Inline filters are the worst! Ive
had them come on three tractors and all three were clogged
or became clogged shortly after purchase

Get ready for the flames! They are coming. I put a brass elbow and shutoff, connected to the carb via a rubber hose with an inline filter I got from Napa, and it has been runing that way for well over 15 years.the filter has been changed a couple of times, and the last one is a se-through deal that you change the guts in. The key is to get a filter that will work in a gravity flow system.

I have found many that leak because of over tightening. Hold the bowl in place without a gasket and you will probably find it rocks back and forth because the top is bowed. I have had some success in straightening them. Install with a soft cork type gasket and do not over tighten. The hard black rubber like ones do not have enough squish to seal an imperfect surface.

Where do you get the cork ones?

Good luck with your water seperation!

If you can't get the sediment bowl to stop leaking probably you will not be able to get the replacement to work any better. It's plumbing and it can be problematic but it does work.

Did a search for "Petcock 3/8 NPT 90 degree" and came up with tons of them made for gas tanks with screens and connections. The one pictured was made for hose connection but they have many with hard line connectors.

Sounds like any hot rod or motorcycle shop carries them. Gonna check my local auto stores tomorrow.

K-MO is right on about the rubber gaskets being worthless. My local independent tractor dealer sells cork gaskets for $1.

I have never seen water laying on the bottom of a sediment bowl.

I just put a new sediment bowl assembly. on my 504U but I cheated a little. I used one for an 8-N Ford with the built in reserve, it is a little snug but it fit, and when I run out of gas a 1/2 mile from the house I don t have to walk anymore.

If you do away with sediment bowl you will not be able to stop moister from getting into carb. If you don't keep tank full to top or they will sweat due to temperature changes.

Farmall Bob · Apr 7, 2011

just take the bowl, some 320 emery cloth, and a flat surface and carefully make the bowl smooth and flat. Make sure the matting surface doesn't have any old gasket material stuck to it.

The sediment bowl wont keep moisture from gettinto the tank. I have one ive been using for years and no problems but the tractors dont set out in the rain and snow.

gene bender · Apr 7, 2011

Of course they can get plugged thats what they are supposed to do is catch dirt so you have a bad tank or bad cans used for filling.

Most regular gasoline these days comes with 10% Dry Gas added at no extra charge. The "moister," aka moisture, never builds up.

Exactly. Not too mention those tiny little bits of rust that will plug an in-line filter in an instant.

I have seen water in the bottom of a sediment bowl. Many, many times.

Every single one of my tractors with a sediment bowl leaks. Even if it's the original one, or a brand new replacement one. Not one of them doesn't drip while the valve is open. They all drip from the same place, the needle valve that you open and shut, not the fuel line or the bowl gasket. I've also tried putting just an inline clear filter on my Super C, and it kept starving for fuel.

If it's an original bowl, you need to either replace the packing, or just tighten up the packing nut. If it is an aftermarket bowl, the lever needs to be tightly closed so it seats, or turned wide open so it seats. Anywhere in between fully closed or fully opened and it will leak.

Rusty is correct, there is no in-between on any of those fittings.

NawlensGator · Apr 7, 2011

What is it with the sediment bowls? I have 3 tractors with them and none leak. I use the rubber gaskets and brass screens from the IH dealer. I usually clean each one out every yr or two and keep everything tight. I like the glass bowls because they allow you to keep water out. Filters produce pressure drop to in already marginal system.

WE seem to have a lot of sediment bowl fans and there is nothing wrong with that. I have one without sediment bowl and in 20 years it has never been a problem and I have some with sediment bowls and have no problems rhere either. May be wrong but don"t think anything made in last 40 years has sediment bowl.

Enar · Apr 7, 2011

What if you run out of gas 1 mile from the house??

Jim Becker · Apr 7, 2011

That's because nobody wants to go to the trouble to clean a glass bowl and a screen. They'd rather buy a new plastic and paper filter and throw the old one in a landfill.

Sediment bowls should be outlawed.

I immediately replace sediment bowls with a close nipple coming out of the bottom of the tank, then to a T in the vertical position then a 3" nipple and a cap at the bottom. This acts as a dirt leg and catches all the big chunks.

Out the horizontal side of the T put a 3" nipple then a ball valve and then a MIP X insert adapter then go to fuel hose and and inline filter from Napa.

It's bullet proof and you'll never fight a leaking bowl or valve that won't shut off tight.
Also you'll never have the top of the sediment bowl fitting clog requiring the complete removal of the sediment bowl from the tank.

What a PITA that is.

I have read the guys poo pooing the inline filters plugging up too fast so I bought extras to carry with the tractors. It's been several years and haven't had to change one yet. I suspect the dirt leg I installed catches all the big stuff.

Try filter part number 21111, it is for gravity feed fuel systems, and is clear also. If you take the old one off and lay it aside, when it drys out you can just shake the dirt out of it and use it over, if that is a concern for you.

I gave up on my bowl last year after trying them for two years because the openings in it were too small and caused my puller to starve for fuel. I never had water appear in it either, guess that 10% water absorber really works in that regard!

I think I will add Dean's idea of a dirt leg to my system as well.

Dellbertt · Apr 15, 2011

This is the gravity inline filter that I have used for years on all my gas tractors. They all run excellent with no problems of any kind. It is available at all local auto stores for about $3.
