Threaded Gas Tank Flame Arrestors.
 

Hey guys, I'm thinking about making some repo threaded style gas tank Flame Arrestors. Is there enough demand for these? I'm a little guy with a lathe and Mill in my garage. I had a hard time finding one as they run about 50.00 average on Ebay lately.
Just curious as to how many need one at this time.

Since they carry the tabbed variety, I would contact Syder's and Btatton's to see if they would carry them, how much they would pay, and how many they would want.

I think pgerhardt has an idea. Could you start with a repro tabed arrester and modify it to be like the threaded style? I had several threaded arresters cad plated a couple years ago, so I am OK for my 4 model A's. It does seem the threaded style is hard to find in good condition.

I think they Bratton's Synder's list the filler screen as drop in's? Unless you want an original
Bert's in Denver might have an original :-)

Drop in arresters are the later ones with tabs. The early ones had threads and screwed in to the gas tank - 28-29's.

Forget Ebay and look other places. The arresters are very common and can be picked up for ten bucks or less. I quit looking at Ebay. Their prices are higher than a swap, and you don't always get what you are paying for.

Must be a local thing that there is so many in your area. I've been to quite a few swap meets and a pile of auctions and have yet to see a screw in one for sale locally. Might be cause I'm in Nebraska :)

I only have one AA and it still had the screen but if it didn't I would have been searching for one. Never asked the question of Bert's if they have buckets full of them for sale or not. If they don't I would think that there would be a market if you could sell them for a cost that makes you and the buyer both happy.

The repro flame arrestors are all drop in. The original threaded ones are around as well as the tabbed ones.We do not have buckets full of them, but maybe 100 or so. Not too hard to find, but generally $40 or so. I think it would be a small market for repros that were threaded unless they are $20 or less retail. Keep in mind that 80% or more of all Model A owners do NOT use them at all.

They were a real pain and most removed them and threw them away . I've never known anybody that used them.

Re: Threaded Gas Tank Flame Arrestors.
 

Purdy, I agree. I've had 2 Models A's over many years, and neither had them, don't see any reason to start now.

I've had no real problem with mine.

Re: Threaded Gas Tank Flame Arrestors.
 

I have used them in my two Model A's and while you can't just stick the gas nozzle in that tank and have it on auto fill, the amount of time holding the gas filler is not that long. There was a reason to put them there and as I have them I leave them in the tank.

I use one in mine. In NJ the gas jockey has to pump the gas. I had one get a little rambunctious and bend the rod on my fuel gauge. This stops the pump nozzle from hitting it.
Don't know if it will arrest a spark, but I am not going to try !

I tried one in the coupe back in the 70s and it was a real pain tring to put in gas without the pump cutting off. Undoubtably the gas pumps in my area pump faster than the pumps in some other areas. I removed the flame arrester and never even considered ever using one again .
