Fitting an Inline fuel filter on a motorbike [HOW TO]

I've been having a bit of trouble with my bike lately. It felt like it was being starved of fuel, suspected valves needed adjustment, a fueling problem or blocked jets.

I took the fuel tap off to first check that fuel what getting in to that OK, it was.. that's when I noticed an orange gunky substance was entering the fuel view bowl. Very odd. I ignored it at first which I shouldn't have..

I googled how to fit an Inline fuel filter and posted up on the Huoniao Owners forum (http://huoniao-owners.co.uk/forum) where I got the same answer get a filter, cut the fuel hose and put it in the middle.. job done. It really is that simple.


So my current bike is a Huoniao HN125-8 which also can be rebadged as Lexmoto Vixen HT125-8 and Superbyke RCC.


These are the tools you'll need.

• Fuel Filter
  
• Pliers
  
• Fuel hose
  
• Hose clamps
  
• Scissors
  

I sourced my parts off eBay.

The fuel filter is a regular 6mm rectangular Inline fuel filter (£2), the fuel hose has an Inner diameter of 5mm giving it a snug fit (£2 per metre). The clips / clamps are 9mm (£2.50 for 10).

Installation of an Inline fuel filter is based on an arrow, which should point towards the carburetor. I also made mine point downwards slightly to help the flow of fuel.

After it has been fitted check it a few times for warping due to heat, loosening of the fittings and leaks.




Here it is kind of in action, the space between the fuel tap and the carb is really tight... I had to take the clips out as the pipe wouldn't bend with them on. The 5mm snug fit proved useful here.










Why should I fit a fuel filter?

I had this filter fitted on a Thursday, I rode the bike up and down the road that night to make sure It wasn't too restrictive. I didn't ride the bike on Friday, this is what It looks like when checked on Saturday..






This is what came out of my tank.
