Fuel tank screen

50/8N/Vermont · Apr 23, 2015

The tubular screen that is supposed to be on the upside of the fuel sediment assembly, within the tank is missing or dissolved
and the cause of my recent intermittent fuel flow to the carb due to some fine sediment.
I have since removed and cleaned the tank and am thinking of going with a short length of fuel line, chainsaw type between the brass
pickup tube and use a submergible stihl chainsaw fuel filter for the first line of defense against sediment before it goes thru the 2nd
flat screen and into the glass jar. Good or bad idea?

Why not get a new sediment bowl assembly and be done and also do it correctly??

50/8N/Vermont · Apr 23, 2015

I know your right, keeping it original and all that.
Just trying to use what"s at hand.
It"s mud season in Vermont and fetching or having parts delivered sometimes has to wait.

Does it still have the stand pipe on it??? If yes you do know you open the fuel valve up 2 turns NO more to use the stand pipe part and all the way open to use the reserve of the tank to get you back to the house for more gas but only use the reserve when needed not all the time. I have one tractor that every year when I use it I have to dump the sediment bowl every day due to a rusty tank. Been running it that way for years now and as long as I dump the bowl it does just fine

I was just thinking how much finer the submerged chainsaw filter is than that 1950 screen material that passes fine sediment .
Might get more carb life between cleanings??

Many hardware stores still sell the bronze fuel screen mesh. Just buy a lil sheet, many come in 4x4" sheets. Roll one around a dowel the size of the fuel inlet stand, then solder the seam, and pinch the top off and solder.

I've made new ones for most of my tractors using those finger sized screens.

When the chain saw filter gets plugged you will get to drain the tank to clean it, which might be pretty often. The stand pipe screen is only for the reserve fuel anyway. The top of the screen is wide open and the normal stand pipe is getting no filtration at all.

That sounds like a great idea to me … using a chainsaw submersible especially if you can access it later without removing the tank!

I just bought a complete sediment bowl assembly and found out something tacky about them as people here have said . . . it's the knob.
Even though the knob screw is tight there is slop in the knob to shaft fit. The one I made for my Jube is perfectly snug so I'll put my own knob on if it fits. Either that or stuff the new one with Devcon plastic steel before tightening the screw.

When I make one I pinch the top off and solder so both pickups get the benefit of filtration. Helps some I guess.

Vermont,

I spoke too soon as usual in advocating the chain saw filter.
The chain saw isn't gravity feed fuel and involves a much smaller demand.

I had a gravity feed chainsaw in the 70's; an old Pioneer.
You pushed a lever and the handle, tank and sediment bowl swiveled 45 degrees for cutting sideways.

I"ll be calling around locally to see if I can find some of that bronze fuel screen mesh tomorrow.
Soldering is no problem for me.
Thanks for the info !

Good luck!

I don't know what all is out there , but I do know there are dozens of similar screens used for paint sprayers . There is a wall of them where I buy my paint but I have not YET gone in with an old fuel shut off to match any thing up .

Definitely helps a lot. I was removing my sediment bowl assy every year because there was a lot of sediment that used to flow up over the open top of the screen filter. After that I just plugged it up with the brass pipe plug so the fuel always has to flow through the screen. Never had issue since then.

More likely to get more stalls and less run time when you need it. A sediment bowl due to the way they are made does better filtering then any other filter ever made

Contaminated fuel are fuel tank/supply system will win every time filters, screens are no filter/screen...

Why not fix it correctly in one statement and in the next statement every time I use my tractor I have to clean the screens... So I take it the correct repair is to clean the screens daily....

Fuel will gravity flow threw most any filter I have had the pleasure of replacing even high pressure fuel injection filters. If the filter stops up its doing what it was designed to do :shock: The fix is to repair are replace the source of contamination... Once a tank starts to rust its history it will always win and be a issue unless its repaired correctly are replaced. Filters are screens will stop up. Its called ...Cause And Effect.... answer those two questions and there is no need to ramble on are make up the do's and don'ts.

Don't forget the fuel line its self are the fuel circuit tween the fuel elbow at the carb and needle and seat.... Any place that supply's fuel Till it gets in the carb bowl is suspect filters/screens are no filter/screens...

Steiners has the part you need. remove the sediment bulb and it pushes into the inlet, is about 3 inches long. Very fine mesh heavy screen.

Old,

Speaking of good old sediment bowls … I like them too.
On my International, I installed an electric fuel pump but routed the gas through the old fuel pump with its filter screen and glass bowl.

On my '51 chev I took an old GM glass bowl fuel pump and converted it to a filter under the van next to the gas tank.
I switched the in and out or removed the valve or something . . . so long ago i can't remember

but it is still doing the job.
P.S. I wrapped the bowl in rubber so a stone couldn't break the bowl and I have mud guards behind the front tires.

Ya the U.S. Navy uses sediment bowl sort of things to filter things a a lot. They even use that system for there air systems on subs. Fluids can change direction easy but things like dirt and rust tend to not change direction very easy so they stay at the bottom of the bowl
