Lots of mopeds have rust or gunk in the gas tank. This crud will find it's way into your carburetor and crud it up, causing your bike to run like crud. Nobody wants that! Fortunately there is a cheap and easy solution for this problem... thee inline fuel filter! Follow me, I'll show you how to do it.

I made it at Techshop. They have a work bay where you can work on your car, motorcycle, moped... whatever! There are 3 of them around the SF Bay Area, so it's pretty convenient. There's others around the country and they have lots of tools and workshops. Wood, Metal, Fabrics, Electronics and more. It's rad.

Step 1: Remove old fuel line

Your old fuel line is probably all crudded up, lets replace it. First, turn off the fuel flow at the petcock valve. Then, pull the fuel line off from the carburetor and the petcock valve. Throw that in the garbage, because it's all yuck.

Step 2: Install new fuel line...

Grab your shiny new fuel line and attach 1 end to the petcock valve.

Step 3: Position fuel filter

Now visually position the inline fuel filter. I try to set the position so that the filter is at the lowest spot of the fuel path, so all the crud will get trapped in the filter and held there by gravity. I like gravity because it's cheap and works most of the time. Also, on most inline fuel filters there will be an arrow showing the direction that the fuel should flow. Be sure to take this into consideration when planning the position of your new filter. Don't let the filter make contact with the cylinder or other hot parts.

By the way, never reuse an old fuel filter. Never ever.
