I am a novice at fixing a tractor so please if you answer give explicit details. I bought a 1952 Ferguson TEA20. I had a fuel leak at the valve by the sediment bowl plus I needed drag links. I changed the drag links then decided to empty the sediment from the bowl and find out how to stop the leak. By tightening the nut behind the valve I was told that would stop the leak. So I cleaned the bowl and tighened the nut. I was extrememly careful not to break the gasket for the fuel bowl and after cleaning it and putting it back together I discovered that the leak at the valve had stopped but the fuel now leaks from around the top of the sediment bowl. I had drained the fuel tank completely when fixing the drag links and inspecting the valve and now that I put fuel in the tank all I have to do is open the valve and before I even try to start the tractor the fuel is leaking down the sides of the sediment bowl. A neighbor said I might have an air lock? I did try to start it again and found out that there was no fuel going to the carburator also. Any ideas, suggestions or how to's will be greatly apprciated. Thank you for taking the time to answer me.

My Fergie is running and no more leaks! Thanks to everyone who answered my questions about a fuel leak. The problem is solved, no more leaks and my Fergie is running. Hope I might be able to help someone in the future.

Glad to hear you fixed the leak problem. It"s always nice to get feedback about what you found that cured the problem. Working on these old machines is a learning experience for all of us and you can help by providing some feedback about what you did to fix the problem. I will go in the archives and may help somebody else in the future.

About my fuel leak all I did was wait overnight for the cork seal on the sediment bowl to become wet and expand therby stopping the leak. Then I added much more fuel to the tank and found a thin piece of wire and poked it through both ends of the vent hole in the gas cap. After a few tries Fergie fired and I took her for a little test ride. Seems to be working OK and no more fuel leak. Sure is great to have all those suggesions on what might have been causing the problem and I have printed all the answers for reference just in case something like this happens in the future.

city..., everything Jerry said is right on the money. A couple things to add. The cork gaskets can be hard to get to seal, especially when they get old because they tend to warp a bit & get brittle. You can also get rubber gaskets, same shape as the cork. NAPA sells them, so does about any tractor dealer. I happen to use the cork ones myself, but start having trouble with them when they get a couple years old & replace them. Also, check the underside of your fuel valve body, where the gasket goes. There is often a round piece of screen in there, if it shifts and gets under your gasket, it leaks.

I am surprised Jerry neglected to mention that you can check your fuel flow to the carb by pulling the bottom drain plug on the carb fuel bowl and setting a can under the carb. Your fuel should run out of the drain hole "like a cow peeing on a flat rock" as Jerry usually points out. If it don't flow freely like that, you have a clog in the elbow strainer, fuel line or shut-off valve.

I did ask if he drained the fuel bowl from the plug at the bottom. I did not, however, use my usual descriptive phrase!

There is a cork gasket that seals the glass bowl against the metal part of the sediment bowl assembly. They some times dry out and it takes a lot of torque on the nut at the bottom of the bowl to get them to stop leaking. A new gasket usually works to solve that problem. What nut did you tighten"behind the valve". Are you able to open the fuel valve? That nut that I think you tightned, tightens the gland and packing around the valve stem. You should only tighten that enough to stop any stem leak. If you overtighten it, you may inhibit the valve from opening. Are you able to open the valve all the way? Some of the Ferguson"s have a tank valve that has a reserve fuel position, You rotate the valve open two turns and if the engine runs out of fuel you open it fully and you have access to an additional gallon of gas. (It works because there are two fuel inlet tubes in the valve that go into the tank; one is higher than the other. The valve stem when full closed, covers both outlets. When you open the valve two turns, one outlet port is uncovered. When you open it fully, both outlets are uncovered.) Do you have full tanK of fuel? If not ,try opening the valve completely andsee if that get fuel to the carb. You may only havea reserve supply in the tank.

There is usually a small disk filter in the tank above the bowl. If you have one of these, make sure it clean. It should be if you had fuel leaking out of the bowl.
How did you determine there was no fuel going to the carb? Did you open the drain plug on the carb fuel bowl? If you do that and the tank valve is full open and there is fuel in the tank, you should get a bunch of fuel running out. If you don"t the fuel supply is restricted. Sometimes the fuel elbow on the carb has a screen that gets clogged. Check that by removing the fuel line and the elbow. Be careful removing the elbow; if it"s tight, you have to put a fitting where the fuel line came out or you can damage the fitting whenyou apply high torque to it. if that doesn"t restore your fuel flow, either the fuel line is restricted or your tank valve is clogged or the carb float vave is stuck or clogged. Rap the carb sharply with a wooden block Sometimes the float hangs up and this will cause it to move.
the gas cap should have a vent hole in it. Make sure that this hole is open because if it"s plugged then you only get a little fuel out of the tank before a vacuum forms and cuae the fuel flow to stop.

Hope this helps you.

I had a similar leak and found it was due to the fuel tank cap not having a vent and the pressure built up on a warm day. It shouldn't leak under pressure but the easiest fix is to use a vented cap - at least on mine.
