fuel line issue

[Anonymous-0]

1949 8N - I have what I believe is an 1/8" metal fuel line that runs from my sediment bowl across engine and down toward carb. Just below where line passes manifold heading downward, I added an inline filter. My filter stays full of air. It appears that the metal line coming from the sediment bowl is too small of a diameter to allow air from below (the filter) to bubble up through such that the filter would stay filled. This sometimes causes issues with lack of fuel - especially if tractor is setting still and not shaking around (moving). Seems the movement allows for air to work up the line letting gas in, but still not efficiently. Is this a simple matter of too small of a fuel line from tank? What is proper size?

Thanks,

Dale

You really shouldn't need an additonal filter, there is already 3 oem. Filters and gravity feed systems don't mix well. You could add a high flow filter which is basically just a screen. There is already a good screen in the elbow that goes on your carb..

I have an inline filter. It does not fill but I can see fuel running into to it and have not experienced any problems.

Dale;
I'm not going to tell you what to do with yer "N"!!! But if I were you, I would get rid of your in-line rubber hose attached extra fuel filter and replace your fuel line to adhear to specks. You do not need anymore filters on the fuel line. Put it back the way it was, and just use the filters that were made for your "up-draft, non-fuel pump, gravity feed, fuel system.
Take the fuel line off, and go to your local auto parts store, and ask for a piece of brake line, with end connectors,already on it, (they sell the kind of brake line, that is made to bend yourself, by hand), then go install it on yer "N", the way it was meant to be.
There are three filters already on the fuel system, that was made to be used. Added filters will eventually give ya fits.
Here is a pic. of those filters and placements:

Your "N".......your choice!!!!!!!!!

There are a number of reasons why you see non-OEM parts on these tractors, chief among them being ignorance, laziness & lack of money to replace the part. An in-line fuel filter is cheaper & easier to install than it is to replace a gas tank. But, sooner or later, that filter will clog up as well, just like the three screens that are already on the tractor. You can clean the tank & line it, or replace it. Or, keep replacing fuel filters & cleaning screens when the tractor stops from fuel starvation.

My "lawn mower" 1950 N came w/ an in-line fuel filter. The first time I had a fuel starvation problem, I knew I could replace the filter & get another few months out of it, but I just removed it & keep the screens clean until I get around to repairing or replacing the tank.

Dale.......I have a contrary view of yer extra fuelline mounted filter. Air is good, that means it ain't stopped up. You see fuel, the filter is pluggin' up and needs replacing. Iff'n yer fueltank vent is clogged, you will have idle fuel supply issues. (un-screw yer fueltank cap) ......Dell

Thanks all for the advise. Dell(WA) - you are right. I added the inline as an "extra" measure of protection. My tank is good / clean, etc and my OEM filters are in place. For years, the in line filter did not fill with gas and I had zero issues. Lately, I do see a small amount of gas in it. Probably backing up and restricting flow some. That being said - it tells me its at least doing some filtering. Just requires some periodic maintenance if I want to keep it around. Thanks all - good advise.
