Here is a replacement filter for the crappy stock fuel injector filter. This filter goes into the fuel line and you remove the stock one. I was installing one on my bike and figured I would shoot a video of it first.
I believe the husky has the filter in the tank. I didnt take the fuel pump out so I now have two filters. There is not an inline fuel filter on my bike or one in front of the injector. And to answer your question yes the filter can go anywhere in the line.
