Here's a quick and dirty How To on making your own glass fuel filters as shown in the picture below.
The materials needed are: wire that you are using for fuel line ( i used red in the above example and in the how to), #0 crimp beads (the ones that I used are Beadalon brand that I got from Michaels), glass "tube" bead (i got them from michaels but don't remember the brand name), and glue ( i used superglue, but most glues should work)
step 1: put the beads on the wire...crimp bead, tube bead, crimp bead.
step 2: glue first crimp bead on the wire would you want it to be, followed by glueing the tube bead, and finally the other crimp bead.
In the words of Porky Pig...That's all folks!
