    Well thats a bummer
    I kinda like my TR and when you see what the others are offering (KLR, DR, XT and the KTM) the TRs a bargain with FI.
    5 years & 67k klm's it has Never let me down.

    I love the bike the fuel leak around the pump is really getting to me I dread fueling it up

    I need to determine : does it matter if the bike is cold or hot? then it would be the pressure if only hot engine causes the gas expansion but I gutted the vent cap
    never had issues with tank overflowing after a ride in +90 temps
    need to work more on it I guess
    I didn't use specific torque value lightning it just a decent hand feel
    I don't think the metal ring can have anything to do with it It just holds the pump in place...?!
    will post some pictures of the tank after I take the pump out again

    thank you

    Hi jetsun just wondering how you went with fixing your leak issue? I have a feeling the brass screw holes might be causing my leak as well.

    Hi Antti

    Didn't fix it yet
    I have ordered the Versachem tank repair kit suggested by glitch_oz , I'm attaching screenshot from amazon.
    I'm kind off desperate at this moment, Im intending to try to pull the brass sets out of the tank and reset it with the epoxy kit, found out that other are loose too
    you can put the screw a bit in and try to wiggle you will see...
    if this doesn't work then I'm going to replace the tank I guess
    Interesting enough Bike bandit is listing two tanks?! see the pict attached, two different part numbers , price is double on one of them...
    I called the rep and he told me both are available to ship , one is taged :for American market?! couldn't tell me more info nor technical difference if any

    any body knows whats up

    The leak became a problem after I lowsided a couple of times during a BMW rally, trying to impress people with my sliding skills or rather lack of it.

    I think the design of the fuel pump, free floating in a way inside of the tank, allows for this
    when you fall the weight of the pump exerts prassure on the ring and stresses the brass screw sets ?! that is what I suspect...may be wrong

    here I'm thanks for your interest
    also anybody who replaced the tank on Terra and has some pointers please share

    I'm pretty sure there is only ONE!!! tank for ALL models!!! Strada/ Terra/ ANY location on the globe...
    I'd buy the cheaper one....






    Wouldn't be a surprise... the TR-"engineers" seem to have been on some heavy-duty vino when tasked with the job.
    I think it would be wise to remove, clean, dry etc any loose and easily removable inserts for repair first.... before trying to extract + fix the rest.
    From my long-time background of working with all sorts of plastics (part of my job)...this should work ok if done "by-the-book" (read instructions carefully).

    There's also the option of looking out for bigger/ differently shaped inserts for further/ later repairs, should the first repair eventually fail.
    The bolts are only standard M5's, I think...M6?...can't remember, only took the pump out once (to have a look)

    ...gotta check (got one of those), but I thought that was just an extra/ separate part.

    yeah...same part numbers as in Bike Bandit post, same price difference

    I find it interesting and why the hell would the tank cost double in USA....man?!

    the red funnel is really pain in the arsch because it allows you to get fuel only from the left side so you can properly feed the nozzle into it...
    well what the hell
    I'm riding my terra like a hooligan carefully putting only some 2 gallons of fuel each time to avoid the leak
    first cold days Im draining the tank and doing repair
    will take some picts and post
    if that fails it looks like replacing the tank will be my winter project

    I'm sharing with all of you what have been done

    It took a lot of testing to determine where exactly it is leaking
    initially I thought that the gasket is bad....NO!

    or the fuel hose union is bad....NO!

    and then the breather hose is pinched...NO!

    so then I started digging with a scalpel around the brass sets screw holes for the ring
    I blocked off the gas tank opening by wrapping some plastic around the gasket and putting it like that

    then I cut all around the brass sets with a scalpel and discovered that 3 of them have a void on the side of the opening and you can actually see the cream lining of the tank
    I made the cutting deep enough to be able to insert tip of of a thin syringe

    after a long research I chose to fill the gaps and the voids with JB Weld Plastic bonder
    the tank is made with some polyethylene based thermoplastic and JB Plastic bonder claimed to stick to polyethylene

    here are some pictures of filling before sanding
    it sets in 30 minutes but I waited 24 hrs

    then all I did is sanding with 120 grid and 220 final to make it extra smooth
    cleaned the residue with some alcohol and reinstalled the fuel pump

    initial impression after sanding very positive it looks like the compound blended tight with the tank

    I made a temporary cover for the opening by tracing the gasket on 1" thick foam insulation
    and inserting it in the tank as you can see
    no dust got in the tank

    with great excitement I reassembled the fuel pump and started the bike with a little bit of gas in it

    rode it some 20 miles and went to the gas station filled it up to the top !


    no leaking ....man I missed the bike man I'm happy


    this is it

    I noticed that now bike doesn't smell like gas like before it used to

    thanks for reading
