  • Yes. I have said before it is a pity it is translucent and looks an eyesore, looks like it is crying out to be changed but being charcoal it is natural black. A lifetime part but note the comments in the current lifetime gearbox oil thread.

    How the charcoal filter sits in the fuel deiverry system.

    I have yet to tie in the charcoal filter with this diagram but looks like 4 is its feed.

    Next need to formulate a mad theory as to why a leaking seal on a faulty fuel cap accounts for the hesitation and a new cap cures it.

    Finally if you Google something like ‘fuel cap and engine faults’ lots of US hits about causing EML!
