Hi Steve If you look back at your video on top of the 4 retaining clips that latch onto the petrol pipe, there is a plastic ring that sits on top of the slips. The top of the clips are fashioned at 45 degrees. The idea is when you push down on the outside plastic collar, this pushes down the plastic ring which in turn pushes down on top of the 4 clips and opens them up to allow the petrol pipe to be released. The problem with the design is there is very little clearance on the underside of the plastic collar and the top of the petrol pump. So If there’s any sand or grit that get wedged between, this may stop you pushing down on the plastic collar and not allowing the plastic ring to open the plastic clips. Also the 4 plastic tabs on the plastic collar that push down on the plastic ring get distorted upwards over time which prevents enough pressure being applied to the plastic ring again to open out the 4 retaining clips. To be fair the whole design is a bit of a “dogs dinner” 😂not sure what’s wrong with a good quality adjustable clip over a rubber pipe, we’ve used for over 100 years!! Great vid Chris
Thanks for the reply Chris. I've heard that explanation before but there is no clearance underneath the collar on my fitting. With all of the trick "push and snap" fittings on the market (such as the ones KTM uses) you would think Ducati would have a better setup. Especially at the end of a high pressure fuel pump. If that connector is not properly seated it blows fuel at a high pressure. It could be a real fire hazard.
I don't understand why motorcycles so frequently use the cheapest pieces of plastic junk when it comes to the fuel line connectors of all things. You'd think that not having fuel leak directly down onto a hot engine would have them going a different route. Seems like a simple, metal snap ring setup would work, since that goofy plastic "basket" is just there to keep the nipple inserted. It just makes modern bikes (and cars for that matter), just seem so cheap and disposable.
Yeah, you would think the lawyers at Ducati would look at a part like this and think "that's potentially a huge liability, we should probably fix that". If any of that plastic fails, you're dumping fuel at a high pressure onto the engine with a plastic gas tank between your legs!
