Super C gas valve/filter

My original gas valve/filter on my 1954 gas fired Super C Farmall was pretty corroded and the filter screen rusted out of it, so I decided to replace it with one I bought from Orscheln. The new one went in ok, but when I turned the valve on with gas in the tank it leaks around the glass bowl. The rubber gasket inside just seems to want to slide into the center inside of the glass bowl and leak. And I don't see how this rubber seal trapped between the glass bowl and the filter screen pushed against the metal body is supposed to seal anyway. I would think that the gas will just leak horizontally through the screen to the outside. What is the solution to this problem? Or are these gas valve/filters just no good?
 
make another gasket and put one on each side of the screen. that"s the only way I could stop mine from leaking. and have a good new year
 
I sure haven't had good luck with sediment bowls. Seems they leak after only a few cleanings.

I replace them as shown in the picture. The correct police sure don't like it. But it works and never gives me any trouble.

Make sure the filter you choose is designed for gravity flow. I arbitrarily change filter 1 a year as part of my routine maintenance.

I believe the screen is supposed to rest below the edge of the bowl. As to whether or not they are no good--farm store tractor parts are usually not as good as name brands, don't know if CaseIH still sells them. I have bowls on 8 Farmalls/Internationals, none of them leak. A lot of people use an inline filter, I have never needed one.
 
Thats your problem getting one at Orscheln the rubber gasket is the wrong size screen goes on the sediment bowl then rubber gasket get the correct size and you will be good to go. Take your glass bowl to an auto parts store and get the correct size. Mite even have the wrong size screen it is smaller than the rubber gasket. Check your metal base on the sediment assy to make sure it isnt sprung as lots of pliers were used to tighten the bowl and in the process sprung the metal where the gasket seals.
 
Those do work just fine have used them for yrs and they sure collect a lot of fines if the tank isnt perfect clean.
 
The original filter/valve on my 54' Super C has been leaking through the valve for the last few years. So that is why I bought a new one. Sometimes when I turn it off, gas continues to leak through the carb, even when the engine is not running. And I tried a new float valve and gasket in the carb and that didn't solve the problem. But the carb doesn't leak gas when the engine is running.
 
Make sure it is put together right. I use a non-hardening silicone such as Molykote 111 to help seal the gasket. I reuse the old one if it isn't torn & have no problem with leaks.
 
I have messed with these tractors for years. I have found that the rubber gasket squashes out every time as you are finding. Get the correct size cork gasket or make one to fit the housing. The gasket for the short bowl is slightly smaller in diameter than the long bowl. There is a difference.

The screen goes on first then the gasket. The gasket seals the screen to the housing.

Don't mess with any sealers as the gas will attack it.

Don't switch to the external filter. Keep it original if possible. They work very well as they were designed to. And when it gets sediment in it, you simply dump it. No need to replace a filter.

I have had tractors for years that don't need the bowl dumped. If the tank is clean and the fuel going in is clean, then there is no issue.
