    fuel shut off valve repair kit- any luck?

    Hello all-

    I purchased the shut off valve repair kit (part #13270) to address a fuel leak in my Model A. A quick note to those of you new to Model As trying to diagnose the source of a gas drip leak- if the fuel is still leaking from your Model A in the garage (you can smell the gas) a few days after you shut the valve and parked the car, it's most likely the valve under the gas tank and not the carburetor that is the culprit, even though you see it drip from the carburetor. Empty the sediment glass fuel bowl after shutting off the fuel valve in the cab of the model A (you can just pour the contents back in the gas tank), and assemble the fuel bowl back empty & dry, then return the next day to inspect if any fuel is accumulating in the bowl. That will be your proof.

    My valve looked rather new/modern (I purchased this Model A a few months ago), and I thought for a couple of bucks why not try the shut off valve repair kit? I took the valve apart as instructed, and cleaned the stem and housing inside. There were no grooves or debris present- the surfaces looked almost new, but the packing material was all gone.

    Well I spent quite a bit of time trying to get that packing ring inserted on to the valve stem with the provided paste, and put the valve back together with no luck! I even tried filing down the packing material so it would fit better. The parts would not assemble back with that packing placed inside. Eventually it started cracking from trying to make it fit, as it is made of some graphite based material. It seemed to me, there was no physical way the original size of that packing ring / material would fit successfully on the valve stem and allow the valve to operate. I wanted to know if others experienced the same challenge or not, or if I was missing something in the process?

    I ended up purchasing a new fuel shut off valve, which seemed a waste, but at least now my MOdel A is not dripping gas anymore! And it has a 3 year warranty so I hope not to have to revisit this problem again for a while.

    Thanks, Doug

    Welcome Doug
    I experienced the same thing once years ago. The carb had a good float valve but yet still dribbled and stunk out the garage. After changing the shut off valve it never happened again. The original was scored so i just bought a replacement assy. You would think that a good float valve would still stop the carb leak even if the shut off seeped, well i guess not.
    Did you install a new little stand up filter in your shutoff? It helps to stop fine particles from screwing up ball valve

    On my 29 Tudor, I lapped the carb and tank valves with toothpaste to fix each of them. I installed a filter screen in the tank valve, and a new packing.
    I don't recall if the packing came from A&L, Bert's, Bratton's, or Snyder's, but it went in easy and sealed the handle perfectly.

      What we do is to try to minimize use of the stock valve by installing a ball valve resistant to modern gas. When parked short term, we close the ball valve. With valve inside the car, we remove that valve and place a 90deg. fitting in the bottom of the tank and cut the stock gas line for ball valve w/ compression fittings.(No leaks on floor!) I think the vendors sell these now but most hardware stores have the valves for $10 or so. Not fine point but OK for drivers.

        I have several original valves that I was going to lap this winter. After reading this it may be a waste of time if the rebuild kit packing is not usable. Is there more than one choice for manufacturers of the packings? If there is more than one, which is better and who sells a good packing. I assume it would not be Mac's, so maybe Berts. Rod

          Leaky Gas Shutoff Repair
          by A31Woody
          Is it possible to fix a leaky under tank shutoff while it is still in the car? I tried to remove mine, but it feels like it will take the threads with it if I remove it. Carb is leaking from time to time even after running the car out of gas by shutting off the valve.

          My other option is to put an after market valve in the fuel line inside the engine compartment. If I end up doing this,...

          Fuel Shutoff Replacement
          by Birdhunter555
          Hi All,

          Go figure another question from me

          I noticed the smell of gas in the garage and noticed the carb was leaking. When looking at it, it looked as if fuel was all over it and not leaking in one particular place. The fuel shutoff is in the horizontal off position. I emptied the sediment bowl and checked in about 4 hours and the bowl was half full again.

          Who sells shutoff valve that works?
          by BillEbob
          I’m disgusted with the shutoff valves that I’ve purchased. Just rebuilt a “backup” carburetor that was overflowing with gasoline overnight >> 2 problems obviously, the shutoff valve is not doing its job and either is the float valve, otherwise it wouldn’t have poured onto the floor.

          Can any of you recommend a source for a shutoff valve that does what it’s supposed to...

          1930 Fuel Valve
          by Soapy
          I have been putting off the problem with the fuel valve that I have been thinking may have something to do with my coupe stopping abruptly. Since I put the valve in about 20 years ago, and since it had sat without running for a while, it occurred to me that there might be a bunch of sludge in the pencil filter. The problem was that there is about a quarter tank of good gas which must be at least...

          Fuel shutoff valve frustration
          by wayne1230cars
          I am hoping that I have finally solved a very frustrating problem with a fuel shutoff valve.

          I replaced a fuel shutoff valve this summer. It leaked right out of the box. I tried a second one and it was better but still had a slight seepage. At that point I reluctantly purchased the backup shutoff valve line from Brattons. I still had a slight seepage out of the connection to the tank...

          Gas shut off valve leak
          by carolinamudwalker
          I know this has been covered in the past but was hoping someone has a better answer. I gave up on the original shut off valve after three tries and installed Bratons massive valve with copper lines. This valve leaks at the flared fittings, both at the original shut off valve and the inside flare of the filter bole. I dont dare tightened the nuts any more. Is there any thread sealer that will...

          Fuel shut-off valve
          by Steve Plucker
          I know that the tapered inside part of the fuel shut-off valve should just pull right out of the casing (have everything removed to do so). But the darn thing will not come out. I can move it back and fourth.

          It is more than likely wore out within to remove the tapered part.

          Is there a secret that I am unaware of?

          Thanks.

          Possible leaky gas line petcock
          by Bill Harms
          We are sprucing up our '29 Special Coupe in anticipation of installing a Burtz engine. One issue we would like to resolve is dripping gas. The car has had a problem with dripping gas for as long as I can remember. We first traced it down to leak from the carb, because it was leaking. As it turns out the issue may not be the carb after all. It looks like it is because of a leaking original fuel shut...

          I am replacing the fuel valve in my gas tank and am wondering if I should put any thing on the threads to prevent leaking ?? As always thank you in advance !!

          Rebuilding gas valves question
          by wrndln
          I have posted a question or two about rebuilding 28/29 gas valves. Most people have said to use toothpaste as a lapping compound. I chucked the stem in my drill press and smeared toothpaste on the part that has is tapered. I got nowhere after several "grinding" operations! I don't think toothpaste is "gritty" enough to remove minor grooves. I have talked to a a person that...
