Fuel flow problem

I have a TO 35 Deluxe--it has a steel line running out above the settling bowl but has a rubber line running from steel line to an in line filter--when the clamps are tight fuel will not flow into filter but loosen the camp and it flows freely--of course line leaks when filter is full--thought it might be a vent problem--clean vent on gas cap--are there any other vents or anyone have any ideas ?? Thanks
 
Well if you go back to the original design and you look at the filters,
you should notice all of them are micro screens. Now I bet your in line
filter is paper. It won't work with a gravity feed fuel system.
You need the screen filters. One in the tank, one in the glass bowl, one
in the carby.
 
I have run a inline fuel filter on my TO35 for years,
You must ask for a free flow in line fuel filter as the fuel travels to the carb by gravity flow,
I always use a metal cased filter,

I know the tractor left the factory with plenty of fuel filters, but over the years, the fuel cut off valves get replaced with cheaper units that do not
have a screen on the top of the fuel inlet tube, tanks get crud in them, transfer tanks have crap in them, even the fuel stations do not always
change their pump filters,

I have had much better results using the inline fuel filter,
 

Fuel filters used on ride on mowers that don't have fuel pumps work . Gravity fed motorcycle engine fuel filters work as well .
 
this is the one I buy, so far so good,

Are you saying no fuel flows through the filter, or are you saying the filter housing will not fill up? It has been my experience, if you remove the line at the carb or open the bowl drain, you can observe the fuel flow, the filter housing will not fill.

I have a rusty tank on my 8N (gravity flow system) and run inline filters to insure clean fuel at the carb. The first filter from my stash of parts had a metal case. It plugged in a few weeks and I removed it. I cut it apart and verified it was full of rust....must have been a table spoon of fine rust packed in there. The next filter from my stash of parts had a clear plastic case. I was puzzled since it never completely filled with fuel. However, the tractor ran fine until the filter plugged a month or two later. Once the tank flushed out the filters now last 1-2 years before change out. Note: none of the clear plastic filters I install have ever run full with fuel.

I have a clear plastic filter on my 16 HP Kohler garden tractor with an electric fuel pump. I have never seen the filter full of fuel, the tractor runs fine.

I suppose a metal case filter would be best for tractor applications. That would prevent damage from tree branches etc. and people from asking about the empty filter housing.
