    A forum member suggested I make this a sticky thread. This applies to bikes with internal fuel pumps.

    I've found the easiest way to disconnect the fuel line is to disconnect the electrical connector to the fuel pump then do a start cycle. That relieves the fuel pressure and the connector is then easy to remove. The design is similar to an air chuck, so pushing on the line while pulling the collar works.

    I think it is OK to post this link here? Nice short demo on YouTube. Only difference is that it won't squirt if you follow procedure above.

    Good video, but other bikes are different. The ring is on the line, and the elbow stays on the fuel pump base. Thanks for posting the video.

    LOL. 3 guesses who made that video several years ago.

    It was part of the carbon canister removal procedure for the Stelvio.

    My vacation plans, someday, tour Italy, eat, drink wine, see the sights. And bitch slap the guy who designed the ( "quick" connect). And the guy who designed the air box on my Stone, a general ass kicking for him. The Gas cap designer, a long spiel of cursing. Fondle their teenage daughters. Make crude passes to their wife & girlfriends. And mommas mia.
    Maybe, A group tour?

    OMG The quick connect is SO DAMN EASY to disconnect. I made that video above. 2 seconds, and it's off...

    I don't get the stress people experience with it.

    You'll have to go the the UK for that. The style shown in that video (above) is a John Guest connector (or a copy thereof). The connector on the V7iii models is quite different, but no better - until you know how. The hint about relieving the fuel pressure works a-treat. With a little practice it becomes quite a quick and easy process. I take my tank off any time I want to attack stuff under there now. Wiring in accessories becomes a complete doddle when you can get your hands in there and see what you're doing. I was quite daunted the 1st time though, I must admit. Takes all of about 60 secs now - including removing the bolt. It's definitely something I'd be willing to do on the side of the road if the emergency required it.

    If it is so easy, why do I see folks on various forums struggle with it ?
    Even after releasing the pressure.

    People DO NOT listen to directions. It's an endemic problem in the USA which I've experienced all my 54 years.

    That and the fact that some people, should never try to do anything mechanical to their motorcycle. Everybody is not mechanical inclined, contrary to their thought to the contrary.

    Lastly, as demonstrated in the video, you don't even have to relieve the pressure. It's not that significant.

    agree...but, for guys who have removed hundreds of fuel lines, with clamps and connections of all kinds, a "quick connect" should be just that. They are all not.
    When it is difficult to remove, One should not have to look for Directions, and spend 1/2 hr on the web looking for the secret handshake and magical trick to remove it.
    It should be simple. No one should have ANY problem removing the connection if it was designed correctly.

    Obviously, many folks have an issue with it, so there is that.

    Well, mine is Not easy or Quick to remove.

    best wishes......

    Many folks think that dielectric grease is used on electrical connectors...

    It's only easy once you've seen how it works. There comes that cathartic "aha!" moment. The only thing which can continue to be quite difficult for some is getting enough fingers into the tight space. You cant do the John Guest style connectors with just 1 hand - at least I can't.

    The V7iii style requires 2 opposing buttons on the fitting to be pressed in firmly (thumb and forefinger) to release the mechanism. It does take a very firm pressure to release. Releasing the pressure in the fuel line helps a great deal with these fittings, but you can do them quite easily with just 1 hand. The fitting on the tank is a "barbed" tube and the fuel line has 2 spring loaded pawls which clip/lock behind the barb.

    Once you get it off the 1st time check it all out really closely so that you'll know what you're feeling for the next time. I had my dealer take mine off during the 1st service to show me how it's done. Once I saw it done and had a good look at the connector I was right. Mine has enough fuel hose to be able to stand the tank right up on its end - doddle!

    I've done the "quick-release" countless times, and know how to do it.

    That said, I share bacon's view of the gizmo and will stand in line -- at an appropriate social distance and wearing a mask :giggle: -- to bitch slap and otherwise punish some Mandellan design folks for it, the airbox on all models, and other weird shix.

    My latest gripe is this display on my Stornello's dash:

    [​IMG]


    WHISKEY TANGO FOXTROT is "NA Int?"

    Turns out it is intended to be short for "Maintenance." :fubar:

    "Naintenance?"

    I say again, "WHISKEY TANGO FOXTROT." :swear:

    As for the tautologically named "quick release," I got sick of 'em and replaced my Norge and Griso's with these:

    Bill, Those BMW style connectors are easy to use. I've used those to replace the fragile plastic ones that are installed by the factory. When I install the pair on a BMW, I switch orientation of one of them so they can't be connected incorrectly since on a BMW, one side is pressure to the injectors and the other is return. You do want to have extra o-rings for them as in a few years they will begin to leak.

    Good points, John.

    And, in my case at least, code for "Bill, check orientation of new connectors." :giggle:

    Thanks.

    Bill,

    You don't need to check orientation on the Guzzi. There is only one fuel line.

    Doh.

    Realized that after posting and just hoped no one would catch me. Should have deleted! ;)
