Earlier post mentioned inline fuel filter problems. I used one on my H and it would run for a while and then slowly get air in it and the tractor would starve for fuel. I could purge it and start over. I could take the fuel line off of the carb and it would flow like crazy. What gives? I have used gravity style fuel filters on lots of things but they will not work on my H. I believe I have seen them on other H"s in pictures.

Sediment bowls are much better in my opinion, they seem to work well for me anyway. There is not a lot of vertical drop in an H gas line so maybe there is not enough pressure to push the gas through the filter? I don't know, it is an interesting question.

There is nothing wrong with the inline filter. The dirt is already in the carb. Did you check the little filter at the carb inlet?

I suspect that you had a restriction creating a vacuum that sucked in air.
I put inline filters on everything. Specifically 5/16" gravity flow from NAPA. Never had any of the issues I hear about in these forums.
I have had far more problems with the sediment bowls. Pictured is the assembly I use.
After cleaning a tank as best I can this will catch anything missed before it gets to the carb. Vertical nipple with cap catches any big chunks before it can plug the filter.

I use these type of filters on everything. Yes I use to have the same problem you are discussing. Some filters are not gravity flow they need some pressure, but even those that are gravity flow, the volume of gas needed on a tractor is much more than a lawnmower so some will cause a vacumn. Be sure to use a large enough filter to allow enough fuel through it. But in all cases I found if you will angle the filter so the inlet is higher than the outlet than it wont airlock. The angle allows the air to go back to the tank when it the gas is first turned on and the entire filter will fill with gas. My 2 cents....

I agree with the sediment screens but i also will use an inline Fram see thru as it will get what the sediment screen doesent.

I do not use filters unless they are for gravity feed. (steel housed filters for Hondas and Subarus with fuel injection are very free flowing and usable, though expensive)
Small filters will trap microscopic particles and become near completely plugged up without showing dirt. When they do, the fuel in the filter can form pockets of fuel vapor. (not air) this prevents passage of fuel even more. Jim

We also call those drip or dirt legs in the plumbing business and use them on lp and natural gas systems.
The blue tape is for water, fuel, gas, oil etc. and is thicker than the typical cheap white stuff. It won't shred in the threads. You can pull it very tight before it breaks.
I know it's not a "correct" set up but it sure is trouble free.

try napa 3031 or 3032 inline fuel filters, one for 5/16 lines , other for 3/8. they are gravity flow metal cannister filters. also, steiners sells a brass screen that fits in the op of the sediment bowl and goes up inside the fuel tank. i have a couple, they work real good.
