Change That Original Fuel Filter... NOW!

wow

Thanks

I haven't gotten around to checking mine out. If it is not better than that one I will be replacing it asap.

which after market fuel filters are suggested?

thanks

out of curiosity, how often should a fuel filter be changed?

I read somewhere in these forums that in 2008 the US govt began requiring manufacturers to use decent quality fuel lines in order to be imported. How do I know if my fuel lines are the good kind or the cheap-o kind? Mine is a 2008 model year so I don't know if it was imported before or after the new regulation.

I brought my scoot to a mechanic to help me out with the pdi. I asked him to replace the fuel filter right away because I was following Big Guy's (?) pdi instructions. He looked at me kinda funny and said "ok, if that's what you want."

Would it be obvious to a mechanic on sight if the fuel lines are the bad kind?

To magnaman,

What awesome pics! I'll never find a manual this good. This is an extraordinary testiment to how cheaply made the chinese scooters are. I think they are making these fuel filters for 25 cents each. Or less.

To neuro, good thinking! You are definitely "ahead of the curve" here.
To lutheheggs, great lesson for all of us to learn from.
To Chi makwa, no it would not be obvious to a regular mechanic to replace cheap parts.
Why? Because they don't use super cheap parts on cars. Car manufacturers know if
they start using super cheap parts the reliability of their cars would be awful and word
would spread and kill their sales.

I once posted a list of flaws I foung in a chinese scooter and was accused of "chinese
scooter bashing". But I never coverd substandard hoses, vacuum and fuel, substandard fuel filters, substand fuel pumps which causes stalling, defective fuel gauges caused by improper installation at the factory, and many other problems hardly ever seen or never seen on the name brand scooters.

My friend has a chinese 250cc scooter that and it won't start due to no spark at the spark plug. We are tying to troubleshoot it ourselves and its not something we wish to do. We think we have a defective part but don't know which one it is. To have a brand new scooter unable to run this (4 months) fast is amazing. It may take us weeks to fix it. If we can't he will take it to a scooter mechanic.

About 99% of Chinese scooters do not have a fuel pump (the ones with the fuel tank under the seat). The few that do are because of the location of the tank. Most scooters only have a vacuum operated petcock (on/off valve) which some people mistake for a pump. It is not entirely uncommon for these things to go bad in one of two ways; either failing to hold open (vacuum leak) or leaking fuel into the vacuum line (fuel leak). On the typical gravity feed, if you decide to remove the vacuum petcock, you should replace with a manual one. At bare minimum, it makes changing the fuel filter and cleaning the carb much easier and safer, though it should be turned to off every time you park your scooter anyway to avoid the possibility of a carb float malfunction or bad line leaking fuel everywhere.

3/4, like inch? Even the EGR line isn't that big. The vacuum and fuel hoses are 1/4" (6mm). If you really are using 3/4 you will never seal off that slack. I can only assume that's a typo... If 1/4 proving too large, you can try 3/16 plastic line (not rubber... plastic will stretch to a tight seal, but rubber if it starts a lengthwise tear becomes useless).
