Hi all,
This is my first technical question so i'll give you a bit of background first... I'm new to these vehicles and don't have much experience of mechanics (a bit of tinkering with a 100cc 2-stroke engine in my schools karting days many years ago and a few oil/filter/spark plug changes since then just about sum it up!)
I've just taken off the fuel filter and following much looking around on here and the wiki and other places for diagrams etc it appears to me (hopefully I'm wrong) that it was on with the flow in the wrong direction . i.e. the flow arrow is pointing back towards the fuel tank... see picture below
I was under the impression that the fuel flow arrow should be pointing away from the tank at this point...
Which way do I put the new fuel filter on
fuel filter direction?

The arrow should point towards the engine.

Re: fuel filter direction?
Assuming it's not come off the 'return' pipe that is, people do all sorts of strange things.

Re: fuel filter direction?
Thanks for the replies. It's not on the return pipe, it was where it should be according to all diagrams just the wrong way round!
I've now put the new one on the right way round but it hasn't solved my issue... if anything it's made it worse ! so I don't think that was the cause of the problem, nevermind - was hoping for a quick easy fix...
I'll look around some more on the wiki/tech archive and then start a new thread detailing symptoms if I can't get to the bottom of it...

Re: fuel filter direction?
Could the fact it's been on the wrong way have caused any lasting damage to the fuel system?

None at all. The pump will just have had to work harder, and it might not have filtered as efficiently.Gavla80 wrote:Could the fact it's been on the wrong way have caused any lasting damage to the fuel system?

Re: fuel filter direction?
The filter media (paper) normally has a support that its wrapped around. The fuel flows from the outside in and the support stops the media collapsing. If you fit it the wrong way around the fuel flows from the inside out and the media could blow up like a balloon once it starts to block up and eventually split. Like AdrianC said it won't do any harm fitting it the wrong way around.
