There are some fairly common scooter projects that are actually quite
simple, but can be intimidating to the novice. Replacing the fuel line
is one of them. The intimidation factor can be traced to the fact that
the fuel line runs under the gas tank, and through the frame up under
the carb airbox.
I was recently working on a Rally 200 which had poor
quality old (though not original) fuel line, as well as a strange
rubbery plastic oil line. In order to get this scooter in top running
condition, I had to replace both the fuel and oil lines. Here we go:
As with every project, get all of your parts together first. Read through these directions to get a sense of what parts you may need, and then buy them. Once thing to consider is that the fuel line has to be the exact right size. Too short, and it won't reach the carb. Too long, and it will kink, and not allow the fuel to "gravity feed" to the carb. The easiest thing to do is to buy the correct fuel line from a reputable scooter dealer. Make sure to have them double check that it is the correct length.
First, you need to take off the seat by removing the three seat bolts. Then remove the two rear tank bolts.
