soundguy - fuel screens

Back in 2007, you posted that their were three fuel screens, one atop the tank tap, one in the tap bowl, and one in the carb elbow.

I see and cleaned the screens in the tap bowl and carb elbow. But [b:c4d528fae2]I do not see a screen atop the tank tap[/b:c4d528fae2]. I haven't found it in the F04 manual either.

Exactly where do I look & see this missing screen. Is it possibly loose inside the gas tank? What does it look like (picture possible?) and if mine is missing, where do I find one?

My tap needed lots of cleaning! If I am missing a screen, I'd like to remedy this.

Thanks!

Thanks, guys. I guess I'm missing the top screen. And the amount of rust showing in the bowl is actually less than their was! I am considering a new tank for sure.

Shoot you got no rust there. I run a A/C D-17 that I dump the sediment bowl out about every time I run it and when done it has at least a 1/4 inch of rust in it. Been that way ever since I pulled it out of a fence row about 10 years ago. As long as I dump it it runs just fine and starts nice and fast and is always dependable
 
Considering that the tank on an N is right above the hot engine
and exhaust, a rusted leaky tank seems like a very bad idea.
They're not [i:3d35d8d350]that[/i:3d35d8d350] much money.
 
I'm gonna go out on a limb here and disagree with most of the gurus. My 9N sat for 20 years and the fuel system was a real mess including a rusty tank. I cleaned it really well and emptied the rust paste out of the sediment bowl regularly for the first 20 hours or so of operation. I plowed snow with it all last winter and accumulated only a thin film of paste for the whole winter. I think the rusty ones can be saved if they're not too bad. I don't have a tank screen either. Maybe it's the pint of ATF I put in every full tank that has stopped the rust.
 
When I bought my barn find 9n. It had the same problem. It
would fill the bowel with rust. I can't remember if mine
had the internal screen or not. It had the other two
screens. Even with the two screens,I still had to clean
the carb often. I made a new fuel line from 1/4 steel
brake line. I modified the new line so I could add a
inline filter right after the strainer. (I know you guys
don't like inlines) The rust problem in the carburetor
went away. I still would get a bowel full of rust. The
rust didn't make it to the carburetor.

Later the strainer valve started to leak and I replaced
the strainer with the correct Ford type with the inlet
screen. That really helped to keep rust out of the glass
bowel.
 
agree with the guys.
the 'red mist' rust that gets past screens doesn't do your carb any good.
And if you wouldn't feel comfortable whacking the bottom of the tank hard with a hammer.....time for a new one.

that said, as most here know, I hate buying anything.
Don't spend that 1 dollar 1000 times...and I can buy another tractor.
or some tractors...just ain't worth new stuff.
If the tank is still sound, taking it off, high pressure water wash inside as I pound the outside everywhere with my hammer gets the big rust out. dry it out, new screens [i:a8db364f0a]and[/i:a8db364f0a] a new gas line gets it back in the game.
(this obviously doesn't stop rust, it'll come back...just gets it running again)
 
You guys probably already now this......

Bought a four wheeler that had sat for a couple of years. Lot of varnish and crap in the tank. I put a can of sea foam, some hot water and a handful of nuts and bolts in it and shook the snot out of it. It cleaned right up.

Same thing would work on a tractor tank to help clean a lot of the loose rust out.
