My dad always ran the gas out of the carb on his Model A and I do the same, with no ill effects.

Usually a pencil filter is recommended that sticks up into the tank and is fitted into the original inside style shutoff. With that style shut off not sure how a pencil filter would be installed. Purpose of a pencil filter is to keep rust/etc out of the fuel valve.

You are correct. This is just a replacement of the interior gas line with the addition of a modern shutoff valve, that could also fail in the long term.

I will do the correct job at some point by replacing the original valve and adding the pencil filter (could be is there already). Could be the previous owner added. But for now I want this faster and easier fix. Not to much time to do the other job.

Thank you !!!

So what you ordered attaches to the original, so is in addition to the original? If so did not know that

Correct. Attaches to the original. Goes from the original to the firewall. You do not need to close the original any more.

Reporting results:

The pictured shutoff valve didn't fit in my 1929 Tudor.

I took out the interior gas line. To find that the long arm that will attach to the original shutoff valve was "too long". It was around 0.4" (1 cm) longer. The tubing is very rigid so there is no way to bent it a bit.

Moreover, the valve will not close because it crashed the GAV rod.

So 2 issues in my 1929 car:

-The Long tubing side was "too long".
-Valve position is incorrect. Needs to be moved to be nearest to the original shutoff valve to avoid the GAV rod (more to the left of its actual placing)

Tomorrow I will call Bratton to check how we solve this. Most probably they will have to refund and I will get an "original valve replacement with the pencil filter". Then I will wait the winter season to empty the tank and do the correct job.

My fast and easy solution didn't work in my car.

Best !!!

Good Sunday Afternoon to all...I have run the Bratton's Shut Off Valve in my fuel line, after the original valve for about 15 years or so. It is very reliable and has given no trouble. I have left the stock original valve alone in the on position all this time. There have been no issues at all...Ernie in Arizona

Forddan,


While a new functioning under tank shut off valve will stop the drip, there is the chance you still haven't found the issue inside the carburetor.


With the gas shut off, remove the lower bowl, set it level on your bench and fill the bowl 1/2 full. Check in the AM the bases of the two jets in the throat, if wet = leaking gaskets.


Same experiment with the float & float valve. Using rubber bands to hold the float up closing the valve, check the next day for wetness = leaking float valve gasket. Also the machined surface where the float valve & gasket sit must be smooth, not coarse & pitted.


Hope this helps, JB

I do not have nothing bad to said about the inline valve as I was not able to install it.

I just said that the design does not fit my standar 1929 Tudor. The long tubing it too long , so I cannot fit it. And the valve arm crash the GAV rod. So you can not fully close or open.

Thank you. I will try this during the winter.

You could shorten it up and reflare it.

Maybe you could rotate it to a different plane?

You are correct. All that can be done. But that isn't my idea of an easy solution to solve my undertank shutoff valve small leak.

Bratton's customer service was EXCELLENT!!!!.

They offer me to do the modifications you suggested, but they concluded that it will be better to refund the $$$.

After that decision I ordered, from Bratton's, the under tank shutoff valve and pencil filter. Winter project.

Again, thank you all for all your comments and tips. They are very helpful for a newbie as I am in Model A and car mechanics.

Best !!!

Update

Bratton's refunded my money. They have an excellent customer service and I bought from them a repro shutoff valve and pencil filter.

I also found that Mikes's A Fordable Parts have the same in-line modern shutoff valve. I decided to give it a try. In this case, the long tubing was shorter and the valve was placed with the handle looking upside. In this way, the handle movement was not blocked by the GAV rod (see pictures).

After an hour of hand reshaping of the tubes, I was able to install it. The connections are not leaking, neither the carburetor. It has been 24 hours since I installed it and so far so good. No gas smell at the barn and all is dry. I tested the car for a mile and all is fine.

That's all. I will keep the "Bratton's original repro shutoff valve" just in case.

Best to all and thank you for your comments !!!

Daniel

I found this video and it's worth watching I believe if you have any flared fuel lines. The guy takes copper washers and makes gaskets out of them.
