29 Truck arrived Monday and runs and looks Beautiful !
But for some reason with gas valve off truck sitting in garage
overnight come out in morning and gas on floor for 2 nights.
So decided to take carb off and found it to be clean but NO filters.
So with draining all gas and knowing valve is not stopping gas flow
completely ,removed Valve. No screen filter on Valve into tank.
But with valve in my hand there was a LOT of Sediment in valve passage and
also in the filter on firewall.

My Question is now that I have tank and Valve off do I screw a hose into tank
and flush it with Kero,water, or air ?

Or just install filters on new valve /carb when it arrives.

Would like to know what others may have done with situation..

If there is crud in the tank by all means install a screen in the valve before installing the valve.I personally would put an inline filter in the system at least till all the sediment is out.I have a micro filter in my sediment bowl but my tank is clean.A micro filter probably will not work for you as you have to much muck in there J.M.H.O.

Thank You ..I just climbed up on top and took a flashlite and looked inside.
It is coated inside like new..
So must have been old gas and sediment from that..
But will install the tank filter and install a inline filter for a while,
I purchased a new gas line and will cut old one to install inline for a while.
I purchased new valve also for shutting gas off.
Thank You Joe
 
While you have the carburetor out you should install a new vitron needle and seat and adjust the float height. Just my opinion.

Do not ever blow air into a fuel tank that has had gasoline inside. No matter how old you think the gas might be. By doing that, you complete two sides of the "fire triangle". All you need then, is a small spark from any type of ignition source, and you and possibly others watching, could be talking to St. Peter at the Holy Gate. Use an inert gas, such as Nitrogen, but only if you must.
 
If you have a glass sediment bowl you might want to install a NAPA Filter #3039 instead of an inline filter as it is much easier and looks better, IMHO.

Just a thought here - and by no means the final answer. While boiling out the gas tank would probably solve my problems, I don't have the resources to do a complete or even partial re-paint of my car. So I opted for the following. This is the sequence I followed before settling on the current solution.

Solution 1...for a limited time this worked.
If there is any sediment/rust in the tank, especially fine sediment/rust, that stuff will grind away on the brass shut off valve and you'll have the same problem again.

As noted - the upright valve filter (http://www.snydersantiqueauto.com/2140) is a must (inserts into the valve.) Eventually though if there is enough sediment, the valve can be covered and restrict flow. So, I had to resort to step 2.

Attempt Number 2. . . Inline filter
An inline filter is a great idea (cutting the line between the tank and the valve is a good place, provided you use a metal or glass filter.) Why? I had my plastic filter installed here and I think (but cannot substantiate) that the heat from my manifold heater was warm enough to cause some 'distortion' of the plastic. I put a glass micro-filter there (NAPA) and did not have the distortion problem - but I did have other problems. The filter would fill up with gunk and I had to replace it A LOT. I also found that the sediment was beginning to restrict the flow to the fuel line (blocking the vertical filter in the valve and the in-line micro filter.) As a result I resorted to the final solution.

Final Solution 3. . . Flushing the tank without removal.
I drained the tank into approved containers after I used up most of the gas on several treks. I then used 8 gallons of Evapo-Rust (shameless plug) which had been purchased for a variety of other rust-busting efforts. I filled the tank with Evapo-Rust and let it sit in there for about a week. I then drained the tank into the Evapo-Rust bottles (it is reusable. I promptly flushed the tank with water and sloshed the water around to the best of my ability (it must have been humorous to watch a grown man standing on the running boards and rocking the Coupe back and forth.) I drained this out by removing the shut off valve completely.

Replaced the valve and filled the tank with 5 gallons of Kerosene and sloshed it around using the above manner. Let it sit for a day, then drained it out.

I replaced the shut-off with a dirty-leg setup (http://www.fordgarage.com/pages/kellyshutoff.htm).

I have since had very little (if any) sediment in the carburetor, but I do have to drain off the dirty leg about once every 5 fill-ups. It's been on there for about a year now and I just drained the dirty leg after 200 miles of driving. The sediment was minimal.

I always top off the tank now as well.

Hope this helps.
 
My tank is very clean, but I always install the filter in the valve. Any speck of junk can scratch the valve and make it leak, and any little bug or leaf or what ever else might fall into the tank can block the opening to the valve unless you have the screen.
 
Harleyjoe,
I had the same dirty gas tank problem that you are having. It kept clogging up and wouldn't run. I found this website www.fordgarage.com/pages/kellyshutoff.htm
I took the picture to my local Ace hardware and they had all of the parts. I built it, put it on and now I drain it before I drive anywhere. I had it on about 6 months and still getting dirt out of the tank. It will probably take a year to get it all out, but you can still drive it. If the car stops, just take the plug out and run a piece of coat hanger up the trap to unclog it. Be sure you have something to catch the gas in.
Did you buy your pickup in Austin, Tx?
