  • Gas tank flame arrestor

    Tell me guys how many people use the flame arrestor (tank filler screen) ? I've asked about it at our club meetings and out of 25 people may be 5 people use them, and about 10 didn't know what they were. I always have one in my tank. So what's your opinion? With modern gas pumps I think we are safe with static electricity.

    I have mine on my car, UNDER THE SEAT! It is such a pain with the pumps and how it splashes. May not be as safe but I have not used it in decades.

      Never used one myself. But I think static electricity fires still happen. A quick search on YouTube shows how: Just walk up to a running pump and zap it like you do your wife on the sofa. Same reaction!

      This important video has been out for some time, now, but is very important. STATIC ELECTRICITY IS A SERIOUS FIRE DANGER for drivers fueling their cars at s...

        I would never have an A without the flame arrestor in place. Modern gas pumps do not solve the differential ground potential problem.

        No one that I know has ever been thrown through a windshield or out the side door during a crash but that would not justify my not wearing a seat belt, either. Your propensity and desire for risk may vary.

          I use mine.
          It should also help to keep the gas from sloshing against the cap.
          This will help with some repro caps that have a vent hole in the center of the cap.
          Or, did someone just drill that?
          Either way, a hole through the center of the cap isn't a good idea.

            modern cars don't use them......

              some modern cars DO have a flash arrestor installed
              mine has a flap that seals the tank ,
              when you push the nozzle in the flap opens

              I have seen two model As burn up completely
              they both had full tanks of gas and the gas tank did not explode or catch fire

              back in the olden days ,the gas pumps had larger nozzles and far les pressure
              the new ones with the small orifice and high pressure are a real pain

            I too got tired of fuel splashing around. Static tricity can be a problem. If you're worried about it I suppose you touch the nozzle to the bumper, cowl light, windshield frame,etc before fueling.
            I've never seen or remember hearing of such fire with a vehicle, but, have seen it with aviation. Once is enough for a life time. If you're a flier don't forget the ground clamp.

              I use mine.


              • #9
                Well the vote is in. I guess I'll still use mine. I try to be safe so I can drive my A again another day

                    in the service bulletins index under cowl tank, it says "filler screen purpose page 311"

                    i looked on page 311 to see what they say the purpose of the screen is but i dont see it.. am i blind?:

                      The second paragraph under "Corrections" mentions the purpose is for fire prevention, and not as a strainer.

                      I use the one that came in my Tudor, and to ease the input of gas I purchased one of those stand-offs that stick in the neck. That sure helps greatly in this land of noxious fume abatement we call California.

                        I drove a Model A for 40 years and never had .... or even knew about Model A spark arresters in Model A gas tanks.

                        I bought one 10 years ago and after 2 years it corroded, turned light grey, and all the tiny holes became partially plugged.

                        Thought about making an orange juice strainer with it until I heard that fresh orange fibers are healthy.

                          Thanks! Never even thought about the taste ..... I'll definitely throw it away on my next garage clean up.

                              About 50 years ago, I actually saw a guy half fill a (1) pound coffee can with gasoline, place it on the ground out in the open, strike a large kitchen match, throw the lit match in the can of gasoline, and watch the match get extinguished in the wet gasoline.

                              I was standing about 50 feet away ..... I would never ever recommend anyone trying this.

                                I use to do that as a kid also. Sometimes just a soup can.

                                I will confess that I never did it "in my own back yard", but in an empty field across the street. (And never told Dad about it!)

                              So when I received a gas tank I purchased I really didn't give it a good once over since the deal was done and guy said it had no dents and was a really nice tank. Got it back from sand blaster....what a waste of money. Huge whammy in the top corner. Nasty welds on upper corners of dash. Looks like fuel valve was snapped or cut off so there is a mess there....nobody will work on a tank correct due...

                              When installing the welt around the gas tank, should I use any adhesive or sealer, or is the pressure provided by all the small bolts around the tank and cowl enough to keep the rain out?

                              Seems like someone is always needing these tank clamps, even though the seller calls them "bushings". Too bad the bolts are gone.

                              I am getting ready to replace a leaking gas tank in my Tudor, I have a very good one coming from Berts, but ..... I'm not totally sure what I should do now.

                              I have read Brent's thread over on the old barn regarding getting a tank clean, by cutting apart and then re-welding. But what do you do AFTER you get it clean? What do you do to keep it from turning back into a rusty tank?

                              I know this is kind of an odd way to start a post. Back about 30 years ago when I began the restoration of my 1930 coupe there was a Redi-Strip near Allentown PA. I had them do several of my parts including the gas tank. The gas tank was installed in the car without any further work done to it except a good slosh with gasoline. Moving forward to now, I'm running with a pencil type filter on the...
