Can anyone figure this out? I always turn the fuel off at the sediment bowl after use on my 50 8n. The problem is when I turn the gas on there is no fuel flow to the inline fuel filter right before the carburator. If I take the fuel line off of the filter, gas flows perfect, then I"ll hook it back up and the tractor will have no problem getting fuel as long as its running. Then when I shut it down, the fuel flow to the filter stops and I have to go thru the same process again to start it. I tried removing the gas cap thinking it might be a vacume problem but that didnt work either. Thanks to all.

| to the original poster,
normal gas trouble shooting,
dirt, restriction, sticking needle valve, etc
(engine should restart on the fuel left in the carb bowl after a normal shutdown)
as far as the inline, I use them under certain circumstances all the time.
ie, repaired carb inlet, cracked, stripped etc
repaired carb body
home brewing a shutoff when no $ for a store run
I stay away from the paper ones, as they don't seem to like water.
I get mine for my WheelHorse tractors, so I usually have a few laying around.
They just have a screen in them, just like an N.
very easy to take out and clean under normal maintenance
on a tractor with a carb I know better than to touch...or a touchy sediment bowl.
most say up to 15 horse, but I've never had an issue with them,
even on engines bigger than an N

| Loosen the gas cap and see if it makes a difference. Mine would have no gas in the top of the bowl until I started it, gas would then start flowing. Under a load or faster running my 8n would starve for gas, the gas cap would be the culpret.

| just my 2 cents worth I am no expert but about 5 yrs ago before finding this great site I put fuel filters in both 8ns (just because).5 yrs. and I never had any trouble with either of them. But I have noticed that after turning on the gas if the fuel filter is dry no fuel moves untill you crank it over but causes no problem.Interesting though I had a 52 8n with no filter, twice I ran it out of gas and both times it wouldn't start and no gas would move in sedement bowl untill I loosend the fitting at the carb.My 46 2n has no filter and 2 wks ago I posted about a fuel problem I had, turned out to be dirt in the main jet I changed the screen in bowl and a new elbow in the carb but neither looked bad.

| Quoting Removed, click Modern View to seeYou seem concerned with whether or not you "see" fuel flow rather than whether or not the tractor will start?? If it actually will not start before you disconnect & re-connect the fuel line, then maybe you have a legitimate concern. However, it is much more likely a stuck needle valve than the inline filter, which is always the whipping boy" in these forums. Hundreds of thousands of gravity feed lawn mowers & other small engine machines use exactly that, inline filter & gravity feed without any problem. I have lawn mower, ATC, log splitter, and air compressor with those same little plastic filters and some have not been changed in over a decade and I guarantee that they are NOT a problem.
But it make for conversation. A proposed problem area when one can't pin point a real problem. Change it or Take it out ........then start looking for the real problem when that doesn't fix it. :roll:

| | i vote for finding the problem and fixing it, before removing or adding anything.. :) the main issue i see with small gas filters is that they are so fine, finer than a screen.. that small 'fines' seem to get them. we have dust here.. and it finds it's way into anything. orange dust. makes it into the vented gas tanks and cans. have seen it in filters.. that and the dad gum water than makes gummy mess. at least with the metal screens and sediment bowls, the stuff just sinks. I prefer those to the paper pleated filters... i imagine in arid environments, the water is no concern... here in florida it is though.. I have half a thoughttha that may be what guns up the needle valves.. emulsified water and fuel by products after airiated alcohol and volatiles and propane evap out.. :)

| Years ago I thought I would be smart and ad a inline fuel filter to my 2n. I had the same problem and scratched my head for days. I ask the guys on this site and the other one the same thing you are asking. They all told me to get ride of that inline filter and let the screen in the sediment bowl and the screen in the elbow at the carb. do their jobs, and keep them clean. Well me being the hard head I am I thought the problem is in the inline filter so I replace it several times and still the problem was there. I stopped by a Ford tractor mans shop one day and told him the problem, he walked over to the parts hanging on the wall pulled down a fuel line, picked up a wrench, walked over to my 2n, took off the fuel line with the filter, checked the fuel screens, put on the fuel line he had, fired the tractor up and said. If you ever put another inline filter on this N I am going to crown you with this here wrench. I have never had another problem with fuel flow. Those screens work just fine.

| Good story, but I don't understand how, in a simple, gravity fed system like the 8n an extra inline filter could be a problem (assuming, of course, it was not left on long enough to clog).

Because those inline filters are made for systems using a fuel pump that pushes the gas through the filters. My 8N has been running fine for 60+ years just the way Henry designed it.

I'm thinking that a flaring tool to do a 14 inch double flare is pretty special!

| Brake line works just fine and will cost you less then half the price of a factory type line your call. I always use brake line any more and if to long I just put a loop in it so as to dampen vibration

| That is why brake line works so well it is pre flared to the correct size plus it is a double flare so holds up better

A power steering pump or alternator pulley makes a good shade tree bending tool .
To the original post , remove the drain plug (1/8" pipe thread ) and replace with a $3 drain cock . If a constant stream of fuel will not flow into a coffee can then you can check one part at a time until you eliminate the problem .
