Glass inline fuel filter?

I have a glass filter, but the filtering part is a mesh of some sort, not paper. Otherwise looks gosh darned similar. I like it, but it's also the only one I've used, so I have no stories for comparison

Don't try to run a paper element filter in a gravity feed system because it will stop flowing after time goes by.
The filters with a fine screen (looks like the one in the pic has that) are the ones to use.

Thanks for the replies. I threw it on the bike yesterday and rode for 40 miles. It ran great. I think it might improve the flow to the carb. Mine is mesh like the one pictured- no paper. I was talking about the stock paper filters.
I made it up this monster hill that I usually have trouble on with ease. I don't know how much to credit the filter because I put an o ring in the carb as well, and pushed in the float toggle where some fuel was leaking out.

That's the only problem with doing a bunch of mods, which one did how much?
It's like I have no idea how my bike runs stock. From the begining I was upgrading, sick bike parts is in my favorites list. Without buying a shift kit I've bought almost all the upgrades from them they have. Except the new billet covers Nice, very nice, just can't justify the cost. They're like racing stripes on a car; look good, don't go no faster or make more power.
Now, if they make a new cover for the clutch arm I'm there. When I had that cover off I noticed the hot melt glue holding in the by-jesus pin (Called that because of mechanics saying, "it'll hold, by Jesus!") Well, it didn't. And 5 miles from home, uphill Digging through the sack of bolts we ALL should be carrying I found a tiny metric screw, a #3 metric. If you have a hot glued retaining pin(the by-jesus pin) pull it out and screw in the #3 metric. 1/2 inch is long enough. The hole is just big enough for the screw to self tap and enough hot glue is left to act as a screw locker.
As far as filters go that's a good one. The glass is tempered for strength and fairly thick to resist breakage and has a huge(for a MTB) surface area for long life. I never got to use my stock filter. After finding out how chump the stock fuel line is(brittle fuel line...)I walked the 1/4 mile to the MotoTech motorcycle dealer down the street and got a new hose. I thought about a filter but went naaaa. I went to install the hose and when I picked up the filter it rattled Back to MotoTech. The filter I got is like a flat pancake with a stainless steel screen, ultra fine. And clear so you can see any buildup.

I noticed that glued in pin too, but kind of just put it in the back of my mind because there seems to be enough on these HT's to go wrong as it is to keep me busy!
That's a great tip on the screw replacement though for the clutch arm. That should be in a sticky or added to the list of things to do on a new build. These things definitely aren't as easy as taking them out of the box and slapping them on a bike.

the things about the fuel filter giving "great flow" is a bot of a misconception.
sure, as long as the filter is not plugged it will flow great. but no matter what filter you have on there, the filter will only flow as much as the fuel line will allow in and out of the filter.
no matter if you have a fine screen filter, or no filter at all, the volume of flow will still be the same because of the 1/4" fuel line. when an engine is running, the needle & seat is opening and closing constantly to allow the float bowl to stay full at all times. as soon as the fuel level drops enough to open the needle & seat, fuel will flow into the bowl. If your float is adjusted correctly, this is how it shoudl work. if your float bowl gets 1/2 way empty and then the needle & seat opens, this is when your carb can run out of gas even tho you have fuel flowing into it. the engine will suck up the gas from the bowl faster than gravity can re-fill the bowl.
so really, fuel flow can only be so good on these engines because of the small diameter gas line. remember, gravity is feeding the fuel to the carb, not a fuel pump like on a car.
you are relying on gravity to feed the fuel. You want minimal bends in the fuel line, an un-plugged filter, and a correctly set float level.
1/4" fuel line will only flow so much fuel, so the filter has very little to do with the flow rate, unoless the filter is plugged solid.

that pin should be epoxied in, not hot glued in. if yours was hot glued, then i would not trust anything on that engine.
