Question about sediment bowl.

I am purchasing a 9N from an older fellow and yesterday we charged the battery and started it up. It ran great until it ran out of fuel. The previous owner had installed a clear inline fuel filter that you can see is empty. The sediment bowl is full, and if opened, gas seems to keep flowing. It just doesn't flow to the carb. I opened and closed the fuel shut off several times. Any ideas?

You will get as many opinions as people on this one. Bought an 8N in 1989. Old timer recommended I put an in-line filter on after two carb rebuilds the first year. She's had one on her ever since. I replace yearly.

The inline filter always looks like it has no gas in it. It has air trapped in it. It is normal. Drove me nuts for awhile. Now I ignore it. If you disconnect the hose from the carb, tip it upright, turn on the gas the fuel will force all the air out. When gas starts running out the hose, plug it back onto the carb and tighten it on. Really make no difference. To see if you really have a gas problem you need to pull the plug out the bottom of the garb. Let it run for awhile. Should pee a good stream. Have fun.

Thanks for all the info guys. I'll give that a try next time I'm out there. I still have to buy a new 6 volt battery for it and pay the guy for the rest of the tractor before I actually pick it up. I just left him a $1000 deposit to hold it for 2 weeks until we move into our acreage.

Tried 4 inline filters on my 8n. Not one would allow enough fuel. Took it off and ZZZZOOOOMMMM, ZZZOOOOO MMMM. Wi Craig

It has been my experience that when my 8N runs out of gas there is still fuel in the glass bowl. However, there is a very slight air bubble at the top of the bowl (hard to see if you don't look close). Hence, you may just be low on fuel in the gas tank. HTH. Rick

I added fuel to the tank, and actually blew into the tank to pressurize the tank, but fuel still not coming out of the hose above the inline filter.

Sounds like you definitely have a fuel blockage somewhere. Keep trying until you find it.

Sometimes these problems almost defy logic.

PS... I have had sediment and particulate matter to get lodged inside the inlet of the sediment bowl up inside the tank. There is supposed to be a screen filter there but it disintegrates in time. HTH

Also a screen in there above the bowl but probably not your problem. I have had that screen clog. There is also a screen in the botom of the tank around to the bowl fitting that screws in there. Also probably not your problem.

Could be the tank is low and you still have it on reserve, say 2 rounds. Could open it all the way up on the valve if this is the case. I've done this several times. I always want that reserve so always run mine just out a couple of rounds.

You can disconnect the line at the carb going into the elbow and see if you have a good stream. If good there then the elbow screen is it.

I don"t think it is the screen in the tank, as when I loosen off the sediment bowl glass, fuel will pour out. I have added 3 gallons of fuel to the tank so there is lots there. I was thinking that possibly the needle valve is plugged? I have opened it up 2 turns, and opened it all the way, and it won"t run out of the line above the inline filter.

Any other ideas?

Fuel won"t flow through the bowl and to the inline unless the carb float valve is open. That"s the way a tight fuel system works anyway. If the carb bowl is full and the float valve closed then there is no place for the fuel to flow. Lose the inline, see to it you get a full-pipe flow from the gas line at the carb, remove and inspect the screen behind the brass elbow at the carb and you should be fine. Clean the screen in the sediment bowl. Hold it up to the light to see it"s clear and clean.
The screen in the tank filters only the last one gallon.

The in line fuel filter is probably where your problem is remove it and don't put a new one in they casue all sorts of problems on these old tractors

Most of those fuel filters are made to work with a fuel pump and don't work well on the system an N has. There is or should also be a filter in the elbow on the carb it maybe clogged.

Soo should I pull the inline off mine???
Seems that if the tank is low I don"t get good flow.. guess that could be the problem...

The only inline filters that work ok on a gravity flow system is the ones made for lawn mowers etc. They work well till they get a little clogged then they start to slow the flow down and cause problems. I never use them on any of my tractors and I have around 20 tractors.
