Hello Everyone,
I've got a 66 F100 that I've had since this spring. It has a 302 V8 that came out of a '69 Fairlane 500. She is worn, but the only real problem thus far is that the engine stalls if I'm not giving it gas. (It has an accelerator cable that sticks but this is actually working in my favor for now) I replaced the carburetor, fuel filter, and fuel pump and after each of these the truck idled and ran better for about 30 min. Everyone said drop the tank so I did. I cleaned it as best I could, and got a lot of rust flakes out but I noticed that If I ran my finger on the inside of the tank a very fine kind of rust powder rubbed off. The stalling problem hasn't gone away, I've been told to take a close hangar or compressed air to the fuel lines. Any and all advice is welcome.
Thanks
Any advice for a new guy?

Before you drop the bucks on a new tank, lets try and isolate the problem.
Does the fuel pump have the large canister filter, or are you replaceing the little tiny inline filters that are also used? If you have the large canister filter, is it full of rust when you pull replace it?
You can rig up a temporary fuel cell in the cab or even just sitting on the ground with a nice new gallon gas can and a length of gas line. If you clean out the carb and fuel pump and put in a new temporary line and tank and it runs great, then you know its the crud in the tank and lines. Just get enough flexible line to make it into the cab and stick the line into the gas can and secure with tight fitting rag (don't try silver tape, it melts).
I got a new line that runs along the frame from the tank to the front from inlinetube.com
To clean out existing lines, I would remove the rubber line under the cab back by the fuel tank (you HAVE replaced that line, right) and use complessed air to blow the crud out of the line. You can also remove the line from the tank that goes down to the floor, but I doubt that one is plugged.
Did you phyically remove the tank from the truck and have a friend slosh it around with 5 lbs of nuts and bolts and 3-5 gal gas? That's a good idea too....
Well, have fun. The more you struggle to get it running well, the better it feels to drive it....

Hey Thanks Ya'll,
I'm going to get some pics uploaded soon. I've been replacing the tiny inline filters, but I got one of the clear ones in there now and I can see a fair amount of rust accumulating. How do I start on cleaning out the carb and fuel pump? ( I believe the pump is sealed) is this info on the web?
I did replace the rubber line under the cab, but I havn't tried sloshing with nuts and bolts yet, guess I'll give that a try.
thanks again

If the residue in the tank and lines is rust colored the PO might have used a lead subsitute product.
The way I clean tanks is to remove the tank and empty it completely. If you have access to a steam cleaner use it to clean the tank. The next thing to use is a car wash that works good too. After cleaning the tank as good as you can go and buy a box of dish washing soap like you would use in a dish washer. Put the whole box in the tank and fill the tank with as hot of water as you can. Let it set overnight, dump it out and steam clean it again. When all the junk an gunk is gone dry the tank compleatly then treat it with metal prep and you will be good to go. pay attention to the fixed fuel pickup line in the tank making sure it is clean too.

Insomniac,
What carb do you have on that '69 Fairlane 302?
I'm wondering if it might have one of those sintered metal inline filters located right at the fuel line-to-carb float bowl connection?
If so, it could be clogged up too....they're easy to forget since you can't see them without disassembling the fuel line connection.

Well cleaning the tank is a good idea. You can also take some wrenches or a couple pieces of logging chain (short lengths) and throw them in the tank. Shake it and roll it around on the ground, then wash all the loose rust you just knocked off out of the tank. Then get some tank coating and coat the inside. If your lazy just spring for a new tank and new lines and you'll be good to go also.
All my tools are hammers except screwdrivers, those are chisels.

Welcome from the far south west chapter, insomniac!
All the above are good advice, but remember an empty tank is more dangerous than a full tank!, watch for any sparks!

Honey, If I say I`ll fix something I will, there`s no need to remind me every 6 months!!

The fuel line from the tank to the pump sounds like the problem. Mine was clogged FULL of a sappy molasses gook from the old gasoline. Remove the hoses from both ends of this steel line and try to blow compressed air thru it. If you can get it somewhat open, you can spray carb cleaner thru it. You will have alot of trouble getting it clean. It would be easier to bend up a new line using the old one as a pattern. That year motor did not use a cannister filter on the fuel pump. But they did use a filter at the carb inlet 
take that filter off and drive a nail thru it and then put a clear inline filter between the pump and the carb. Also put a clear filter in the rubber line just before the pump. This will let you know how far the fuel is making it. and also keep everything clean
