Default Very dirty filter bowl

Guten Mittag!

Here is a general hint for information: I checked the filter ball today and I am scared how much dirt has collected in it.
That is piled up within only 2300 miles!

Thats incredible for only 2300 miles, actually for any amount of miles.

I would say the gas tank needs to be cleaned for sure.

I agree . I also use and recommend the stand up filter that can be installed in the cut off valve . the filter will prevent rust from stopping up the cut off valve or gas lines . If the stand up filter is used , you can probably get by without removing the tank in most cases . I've never had a fuel blockage when the stand up filter was used . Rust and trash will collect around the cut off valve in the bottom of the tank. The filter will prevent trash from entering the cut off valve . Back in the day , I don';t think that the stand up filter was offered . Some would install a SHORT piece of fuel line in the cut off valve to help prevent most of the trash from entering the cut off valve . The main problem with the tube setup is that some gas will remain in the tank and if the cut off valve is removed , you'd better have something ready to catch the gas or the carpet or floor mats will be ruined .

I am dealing with a 29 tank that I sealed 45 years ago and now the ethanol gas has dissolved the sealer which is also letting old rust into the system along with goo. If you have the sealer problem it is a real mess but if just normal rust you may be able to just flush it out good and deal with the rust with filters until it is mostly gone.

I agree with #6 above. Don't worry too much at this stage Werner. Flush out as much as you can , and then flush it again, and again , and keep on cleaning the filter. Eventually all the dirt will get cleared. I wouldn't go to the extent of removing the tank . (unless of course the bodywork is already in pieces!)

When I bought our Little Green Roadster over a year ago, I saw that the inside of the tank was very dirty. Brown-red. Inside mounted was the wire filter tube. Therefore I threw a couple of thick brass nuts into the tank. Always put a little bit MMO in it. (MMO contains esters that have very strong dissolving properties.) In addition, a fine micronic paper filter in the carburetor line.

I was very surprised that so much dirt (not magnetic) accumulates in the bowl. Now I will check the bowl every 1000 mls.

I will not remove the tank. The screws and the slots are screwed up. Not worth it.

Werner, when I had a similar problem I installed a dirty leg. When the rust clears up I will install the correct valve and pencil filter. If you are not sure what I’m talking about, do a google search for “dirty leg on a model a ford”.

Werner,
Wow that is way to much crud. Do they have any filters on the gas pumps at the station where you are buying your gasoline. If the crud is getting into your Model A it is also getting into your modern car's gas tank.

Ian,
thanks for the advice. I was thinking about this T-valve. But the problem is that I am not getting suitable US thread inches for the fittings.
But it's not a problem now that I know how big the pollution is. The large amount of dirt shows that my idea with MMO and scraping brass nuts is gradually removing the dirt. I just have to clean the drain housing more frequently.

Dave,
our fuel purity at the fuel dispenser is beyond question.

I agree. Keep cleaning the screen. If you take it to be boiled out 1 kiss your paint goodbye. 2 it will leak. 3 forget about sealing it. sealing sounds good, but turns into a mess down the road unless you can get it back to virgin clean. The stuff won't "bite" to the metal then it comes off in sheets. If ya take it off, get a partner to help ya, and put a length of chain in it, and woller it around to break up the crud.
