IN-LINE FUEL FILTERS-TO 30

Take your existing fuel line to an auto parts place to match-up the correct ID. Don't ask for metal fuel line, they will look at you like you are insane. Ask for metal brake line, they will smile and be very helpful matching-up your line size, etc. (been there, done that).

You can go with a bigger filter than the current line size, I would not recommend going smaller, or risk starving fuel to the carb. It's pretty common to see plastic disposable filters hosed into old N's and Fergy's... make sure you do a good job. If you get a leak, or the hose lets loose while your working, your gravity drain gas tank will contribute to a Fergy Fireball!! ... Hence the use of steel lines in the original.

Your stock To-30 fuel system should have a strainer in the tank, a separting bowl, and a "secret" strainer in the elbow going into the carb. Under most circumstances, that should do the trick. Just being curious... why do you want to install a in line fuel filter?

I use a filter on mine because I continue to have a very fine sediment in the fuel bowl on my TO-30. The in line strainer at the carb and the disk filter above the sediment bowl does not stop this stuff so I used a Fram G-2 for awhile and settled on the WalMart lawnmover filter because it was a little more compact and was designed for a gravity flow fuel system.( The Fram worked fine but was rather large.) It has worked well for me.
regarding the flaring tool, I don't recommend trying to put a full flare on the tubing. Just a little opening of the mouth of the tube to cause it to seal against the rubber fuel hose. SO the plumbing tool will work. Let the tube protrude about an eighth of an inch into the clamping part of the tool and just flare it enough to open the diameter a little bit.
