    Fuel Line

    My USA TTSE Service Manual says to replace the fuel line every 4 years regardless of mileage.

    I assume this is because of the possible effect of ethanol gas over time.

    I'm wondering if this is really necessary since the fuel line is about USD $106 plus shipping.

    Has anyone who hasn't replaced the fuel line after 4 years had a problem with their fuel line causing a problem?

    The only fuel line problem I have ever herd of was from an owner of a Burgman 400 who had a fuel line de-laminate that caused the scooter to lose power.  That occurred at about 175K miles.

    Earthman :

    Do you have ethanol in your gas in the UK ?

    Mine is one of the early 13's and still has original fuel lines. Each time I have the tank off, I inspect the lines, and they seem ok to me. I'm not sure that means too much, but they aren't cracking, splitting, or looking dried out.

    my '74 Z1 has the original fuel line, and has been running on ethanol gas since it's advent.  They are fine... Albeit they are not high-pressure fuel injection.

    My '13 TTSE has the original fuel lines as well..

    The Service schedule calls for the :

    "Fuel and Evaporative Loss Hoses*

    *Evaporative system fitted to certain markets only"
    .... to be renewed every 4 years, regardless of mileage.

    It's not worded very well, but due to this Service Item appearing as the last entry
    on the Service Schedule, and not together with the other Fuel system Service Items
    that appear on the first page of the schedule, I interpret this as meaning that
    only the hoses used in the Evaporative Loss system should be replaced every 4 years.



    To the best of my knowledge the Evaporative Loss system is only fitted
    for the Californian market.

    Being in West Michigan you may not have this system on your Trophy,
    so I would check that first before buying the hoses !

    It might also be worth an enquiry with your nearest Triumph Dealer to confirm
    my interpretation that the 4 year replacement ONLY applies to the Evaporative Loss Hoses.  :028:

    Cheers  :821:

    Coconut:

    My manual says "fuel and evaporative hoses" , not "fuel evaporative hoses" , so I'm not sure about that.  But I don't know of any other MC make that recommends replacing the fuel line periodically as a maintenance item.

    And I think I already know what the dealer will tell me.   :002:

    The local auto parts store has some 8mm R-14 "Barricade" hose in stock.  https://www.do88.co.uk/product_info.php?products_id=9158  It's a step up from the OEM R-9 hose used on the Trophy.  I'm tempted to get the proper crimp style connectors and fab an upgraded hose for a lot less than USD $106.
