Anyone know how to undo these please

You see the serrated markings around the ring nearest to the tank? Squeeze them as bloody hard as you can...

 

clean, lubricate then squeeze in between the two solid lugs, twist and pull.

 

Pinch and twist. When they get released, expect some fuel to come with it. Paper towel at the ready

 

squeeze, pull, tug and a paper towel. Am I on the wrong forum?

 

Weird fuel tank arrangements, and fuel tank problems, seem to be part of the Ducati ownership experience! I've even heard of them collapsing due to breather failure ....

 

These are much better than the old fashioned clips. Less spillage and two secs to undo. Whats not to like?!

 

Not to mention far quicker and more repeatable on the production line..

 

The fact they're plastic, and will therefore break..?

 

Mine are still going strong and the bikes an 05 , I reckon they've been on and off 20 times now , I did read somewhere on the replacement due to number of removal times , but I forget.
I check very often once I've put em back on after having them off, as I get paranoid of a fuel spillage , one or two uses later I completely forget about them .
They are quite easily not set on properly , on the other hand they are just as easily set on properly . I used to be indecisive but I'm not now I don't think. :smile:

 

They're a whole lot better than Triumph's offerings.

Recall-a-go-go!

 

20 years ago, maybe. Now? I doubt it. Modern plastics are very very good. Case in point - when was the last time you saw a cracked dashboard in a car? In the 80's anything over 9 or 10 years old had cracks, now a 10 year old dashboard is perfect.

 

i have had one break on an 06 bike, but i still prefer them to a jubilee cup

 

Since when has a jubilee clip failed? They never fail, ever.

The hose may have failed, or the human wielding the tools, but never the jubilee clip.

Plastic fails often.

Look at Jordan, ffs.

 

I've had jubilees fail - the spot welds that hold the body to the band can fail, they can rust through and they regularly seize. I've encountered all of these problems. Granted, other than seizing (very common on lower rad hoses and water pumps on cars) the failure of the spot welds is fairly rare, but I've had to cut off many jubilee clips. They are ok, but far from infallible

Oh, I'd rather not look at Jordan if I don't have to thanks....

 

I actually prefer band clamps where possible - if they do seize its easy to get in with a dremel or hacksaw and cut the bolt, releasing the clamp. Pricey though, £3 - £5 per clamp as opposed to about 90p for a jubilee
