Flushing fuel tank

[AudioFreq]

Well it seems my dieing issue is fuel related. I cleaned it out last fall and it poured a solid stream after I was done so I thought I was good to go.

20 hours later I have the same drip drip issue and it is the petcock or inlet screen at the base of the tank that is clogged.
Will drain Remove clean and reinstall.
I just installed new int/exh and carb gasket and checked the fuel flow b4 I put the gas online on and ....here we are. Wow does it sound NICE and QUIET, now!

My question is:
Does anyone have any pointers for how I should go about making sure there is no more FOD in the tank?
Eg Flushing ect and how to properly do it.

There are many home remedies that work, but it seems well worth the money to take it to a radiator shop & have it boiled out. If it's got pin hole leaks, you will find out quickly! If it doesn't have leaks, you can look inside once it's clean & see if you need to line it. I'd say the chances are pretty good that it will need lining.

Interesting.
Last time it was a couple of 4" strips of this stringy, thin, translucent nylon tape looking stuff. It was NOT rust. It looked a lot like dental floss... as if someone had wrapped the threads to the output with some teflon tape or something.

I have read the 50tips many times and found nothing about this or (for instance) whether or not tape is needed on the threads when I reinstall the FSO valve.
I could take it to a shop if that were my intentions. It just seems like I have foreign objects in there which needs to be cleaned out. Boiling might not have much effect on this particular debris and I might just be out the money of a boiling. If I have to take it all the way out of the tractor chances decent that I can slosh it out with some gas.

I will see what I can do once I run it out of gas and go from there.
Thanks for the fast response.

A..F..;
Teflon tape, in the sed. bowl huh???? No surprise here.!!! Don't really understand why some people think that any kind of teflon tape is good to use for a gas/fuel leak. But oh well. I find that stuff on/and in carbs, all the time!!! Not good!!!
You say, that you are not finding any rust FOD...(Navy lang. for Gunkapoo) :lol: ... in the sed. bowl!!?? Very possible that you are spot on, and the tape is/may be the culprit!
Take the gas cap off, and look into the tank, at the corners of the baffles inside. You should see clean corners as that is where the spot welds for the baffles are. If it is shiney clean in there...then you may be right, and will only need to flush out the tank. If the welds have rust on them....then it is time to do what Bruce suggested....a rad. shop boil out!!!, then line the inside of the tank.

JMHO

If you're going to remove the tank anyway, and it has not been thoroughly cleaned in several years (or, more likely... you have no idea what its history is) I suggest you go ahead and spend the $30 or so bucks to have it boiled out or steam cleaned at the radiator shop. There is almost certainly rust fines and other tiny bits of debris that you'll never get totally out by sloshing some gasoline around.
Then, to help prevent further rusting, top off the tank every time you put the tractor away. Less than full tanks have space where the air cools and condenses. That means water in your gas tank. Which means rust. And it's that rust that will clog up your filter screens and carb.
I also pour all my gasoline through a big funnel with a fine screen to prevent any debris in the can from getting into the tractor.

You can put a bunch of BB's in the tank with some gas and shake, shake, shake. the BB's will help scour out the inside. Then drain, dump the BB's (careful, they go everywhere) and rinse thoroughly with gas.
