a filter on the petcock.
AKA, a fine mesh screen

so does the visual (forgot the name) trap anything besides particles? ie water? and if not what would be the positive side to having two filters

I only run a filter on the nitrous bike as having something block the fuel jet would be a total meltdown.
Its a good idea to run filter as its added protection against ruining a good ride due to something stupid.

The fit can be tight, I found this one fits nicely...

110%
The petcock screen is non-visable, and unaccessable.
...chuck it.

These are the filters I prefer, the stainless screen type.
They flow allot of fuel, are flushable, and let you see exactly whats in there.

do you put hose clamps on each end or is it a good enough fit your dont need to? I just bought a couple for mine and the wifes bikes but I worry that the hose wont be a tight enough fit without clamps.

I twist tie a little stainless safety wire on it, but it should stay by friction alone.
Give it a tug, and check it.

I recommend using the larger filters if you use one... I had an experience with the small sintered bronze type on my quad.. I was trying to make my main circuit obviously rich before I started tuning.. went from a 170 main through a 200 with very little change in WOT performance... then after I removed the tiny inline filter it provided an instant smoke screen... Now I just dont trust them... I am sure the larger ones are probably adequate though
