Crud in tank and lines

[Clem Clement]

In a friend’s ‘29, the cast iron sediment bowl catches most of the rust – he has to drain it every time before I drive the car. He catch it in a plastic tube and inspect the rust flakes & etc. That is good news. I hope it works as well in Dan’s 28. If so, then with the micro filter we added he may have a chance with frequenlty filter changes.

Here is more down news: In a dried water bottle I collected a drained mixture of gas from the tank with rust particles and the white muscusey stuff. When I added MMO or ATF(I don’t know which) the white stuff turned black. I let the mixture set a day and the MMO re-separated from the mix. Brent sez the tank will continue to rust after MMO is added; which this kinda proves professional job is needed.

(I'm afraid the micro filter will plug up frequently)
(In my '39 peeekup, when we got him running, I had to replace those cheapo plastic filters every trip. It took about 6 months before things cleared up)

:Isn’t there a way to just flush the tank, over and over, until it clears out?. A late 31 is easy to do, but there must be a way to do the prototypes.

Tuesday, Jim came by about 5pmish and looked over my efforts. I had removed
the in car gas line and showed Jim the debris in the line. He brought a
syphon to empty the tank. But first I tried blowing into the gas line with
the petcock open. There was plenty of bubbling in the tank after which we
drained 3 quarts of new gas out of the tank. One inch of which was water had
come out of the gas and about an 1/8 '' of milky substance and debris. That
collected in about a day and the short drive in my village the day before.
Very frustrating after so many hours on this project. Tank has had a diaper
mop up the remaining gas in the tank and all gas lines loosely assembled. As Brent sez, the tank keeps on rusting and flaking off. I saw a single flake block the fuel exit hole

I have heard of putting a magnate in the tank with a wire on it hooked to the cap so you can clean it off occasionally. Should attract rust and anything else metallic.

If your car is a 28 or 29 removing the tank is not really that hard.

On our 29 keeper we had a rust problem clogging the carburetor. Removed tank and sloshed twice. Making sure area around steering column bracket was covered good. This was in 1981, have not had any problems with carburetor or fuel lines since. Enjoy.

Lucky you. Slosh-around usually dissolves in E10

I'm probably in the minority here, but I've had very good luck with professionally cleaned and lined fuel tanks (none in Model As, however). It's a matter of finding a radiator shop that has the experience and expertise, and that is set up with the equipment to properly boil out the tank and line it with a product that is only available commercially.

About $150 at the rad shop I use.

There is more involved with a Model A tank, of course. Removal and replacement and paint to match. Neither is easy.

There are products out there that will work with today’s gas.

You really have to follow the instructions to the letter for them to work.

I believe if you do it completely right the first time. Don’t take short cuts and follow instructions. You have a better chance of successfully solving the gas tank problem. Enjoy.

Removing the tank from a 28/9 car is easier than a 1930/31 but I have just de-rusted the inside of the tank in my '30, sealed it and reinstalled without needing to touch up the paint and I was working on my own. All it takes is a little care. What I have done will see me out and probably the next owner.

I used R 911 available from Hickory, N C. Comes in concentrated form will treat 16 gal about $50.00 shipped. It has worked for me, no more problems.
