I bought this filter king for my new 1380 project but then I realised I didn't need it after all as I already had one.
So what is a filter king?
It is used to adjust the fuel pressure that goes to your carb - allowing you to tune your setup for fuel economy or if you need more fuel for a power build then this allows you to do that as well. It also has a fuel filter in with a glass bowl so you can see when the filter gets dirty - and its a pretty cool visually
It is absolutely brand new and still in the box.
The filter king is the Larger 85mm size with glass bowl - the fuel pipe fittings are 8mm (5/16).
It comes with all of the brackets and everything, I literally took it out the box to have a look put it back in then a few months later realised I don't need it anymore.
