Default fuel filter

i saw that a lot of builders put an extra filter in the fuel lines between petcock and carb. im going to copy this idea cause my bike quit on the way to work on night and it started to rain right at that exact moment. I later found dirt in the carb and in the fuel line sag. that little filter in the petcock isn't very effective by itself.

The standard advice is to just throw the tank screen filter away. And start minute one with an inline filter.

Pablo, do you suggest just cutting the tank screen out of the fitting or something else?

Whichever style you have. Most just press fit in as little plastic/screen cylinder. Just don't install it.

Mine just screwed into the inside end of the petcock.

Yeah those petcock inbuilt fuel screens are hopeless, mine was damaged from the start, putting an external in line fule filter is the best insurance you can take

I agree the inline filter is the way to go. You can find them at any autoparts store. They are usually in the section where they have the lawnmower oil and such.

I might suggest the paper element filter what you can see through about $4.00 or less at wllmart or your favorite auto parts store.

Yesh, WM has one for 2.96, and it doubles as a reserve tank...it's about a half pint capacity.

This one works fine for me. Also considering that I live on the northern California coast and it rains, drizzles, fogs, etc. most of the year I cleaned out my little gas tank with acetone and coated the entire inside of it with a fuel tank sealer to prevent the tank from rusting. The stuff is expensive but not enough to have to deal with the hassles of clogged carbs and stalling engines when I'm 30 miles from town.
