I have tried several brass shut offs, all of which leak to some extent. Some are very good at leaking. What have you used that does NOT leak and is easy to operate. Puzzled minds want to know.
"Fuel Lube" works wonders on ALL gas fittings---Paul
I have the elbow shut offs on 2 cars and they are always wet and it didn't take long for them to get hard to turn on and off. I estimate the leakage rate to be one tank full of gas in about 10 years...but there is some leakage where there should be none.
I've stopped using them for three reasons. Least important is that they detract from the stock Model T appearance. More important is that they tend to be hard to turn. Most important is that if there's an engine fire you may not be able to reach the valve.
So what to do for a shutoff? Use the one under the tank. I saw this on a TT and liked it so much I'm going to do it on all my T's. Use a piece of 5/16" rod coupled to the shutoff handle. Bend the other end of the rod 90º for a handle, and make a bracket to hold it under the running board. You just reach under the running board to turn the handle instead of crawling under the car.
Jack I use the original style elbow valve from Langs...not the cheap one but the period correct one. Got 3 & they work well. One is a little stiff but none leak.
Can we see an illustration of that one, Steve?
I used bar soap to lubricate the original sediment bulb valve and the petcock. It's impervious to gasoline.
Use an in-line brass ball valve.
I use the "Antique" looking elbow valve from Lang's. I like the looks of it as well the convenience. There is one drawback they are expensive. That being said, it doesn't leak or weep, and it's easy enough to turn. I still have a fully functioning sediment bowl and valve under the tank in case I couldn't get to the one on the carburetor for some reason
All shut-off valves will need maintenance at one point or another. If a valve does start to weep just take it apart and lap the coned sealing surfaces with some Timesaver compound (yellow label) and it will be as good as new. Before assembly use some Fuel Resistant EZ Turn Lubricant, also available through Lang's.
I am pleased with the "solenoid shut off valve" I installed at the sediment bowl on our '12 Touring. On and Off with the ignition switch! I only close the sediment bowl manually for winter storage. Many years of satisfaction.Tom
I have some very nice Ts but I guess I'm more of a driver than a show purist. I have small ball valves on all the cars because I was tired of having to use pliers to operate the brass shut offs. I used the air plane lube that Lang recommended and it didn't make it any easier but I seldom had a leak. I'm happy with the more modern valve as they are very small and not too noticeable.
Ball valve. If you simply must.
All new tank, sediment bulb assembly, feedpipe, and the shutoff at carb in my '26 TT working well, no leaks, and shuts off & on easy with 1 or 2 fingers.
I have one of the "period correct" looking valves from Lang's as a fuel shutoff. About a year after the initial install, it began to weep pretty good. I took it apart and applied EZ Turn fuel lube to the mating surfaces. Not only did it stop the leak all together, but it made it extremely easy to turn. The same was applied to the sediment bulb threads and handle under the gas tank with the same results.
It is nice to have a shutoff in both locations to aid in maintenance.
These ball valves are at any True Value hardware store. They are 1/8" NPT on both ends. Stainless construction with a Teflon ball. 100% flow, the ID is 1/4".
Cost is $6.99 I bought one on Friday.
Why not fix the carb? Bud.
My '26 sediment valve leaks a little, not much, but I wish it wouldn't leak at all. I don't like the smell and I'm afraid of a possible fire. And suggestions? Bar soap, does that really work? I want to keep it period correct.
Will - See my post above.
EZ Turn can be bought from Lang's or online at Aircraft Spruce.
Thanks Dan, I'll give it a shot
I use a ball valve.....not original but is easy to turn and does not leak. The ball valve has been on our 13 for over 5 years and has been problem free.
