    I found the perfect solution after many hours of searching the web and all Moto Guzzi models fuel supply parts listings.

    Breva 1100 part GU01106692 purchased from MSP Netherlands - cost only EUR8.85 compared to new Stelvio fuel pump at EUR765!

    I gently and very carefully removed the grey locking mechanism from the main body of the black tube/pipe connector and it was a perfect fit on the Stelvio. The yellow o-ring inside the tube/pipe below the locking mechanism also a perfect fit.

    Happy Days in Johannesburg!

    Excellent !
    Good job tracking down the parts !

    I’m still nervous about disconnecting that fitting, to replace the fuel filter.
    Maybe I should take a trip to the junk yard and get some practice !

    Ok - after watching Scott’s two videos, I understand how to disconnect the fuel line, I just have to practice doing it blind.
    The V7 isn’t quite so accessible.

    I just made it Stidky. It should also work for any bike with this type of connection.

    when i did the roller conversion on my early ntx i did away with the hole lot and renewed with my own metal connectors and fuel lines , i just left the tank connecter in place.
    I wish now i'd taken some pics ..... but next time i have the tank off i will .
    But a good find that !.... couldn't find anything when i tried which is why i renewed it all .

    I have my Stelvio apart and the tank unbolted, still connected to the bike by the quick-disconnect (what a cruel misuse of words) in the fuel line.

    The fuel lines are the stock plastic lines "shrink-fitted" onto the connectors at the back of the quick-disconnect, at the tee, and at the injectors.

    Can I simply use a razor and carefully cut those plastic lines off of the connectors, take the tank off so that I can change the fuel filter, and probably the in-tank fuel lines that are 12 years old ... and when I put it back together, just use high-quality Gates fuel injector lines and standard FI clamps down to the injector inlets? Maybe when I have the tank off and upside down on the bench to get at the filter, I can worry the quick-disconnect carefully apart and maybe replace it with a metal one or leave it be.

    What does the panel of experts say?

    Don't cut the fuel line. Learn how to disconnect the fuel line properly. see https://www.guzzitech.com/forums/threads/removing-fuel-line-quick-disconnect.20279/

    John - What I was thinking is that that plastic fuel line has been on there for 12 years and 60,000 miles, heating and cooling, heating and cooling .... So I figured as long as I have fought my way through those hedges of swords and briars known as the Side Fairings and Front Fairings, it might be a good idea to replace those possibly-fatiguing fuel lines anyhow while they're accessible?

    I was going to do the same with the fuel line inside the tank when I replace the fuel filter. Is that not a recommended thing?

    The lines Guzzi uses outside of the tank are very durable. Leave then alone. The internal lines had some issues in early bikes, but later ones are also very durable. Be sure to sure to use Oetiker or fuel injection type screw clamps when replacing the fuel filter.

    I had repositioned the external fuel lines and found that I had kinked one and so gas delivery was not all it should be, so I purchased a replacement line (about $66 Canadian, so about $12 American:D). Runs better now and I always have a spare, for whatever reason you need a spare fuel line for!

    BrianR - Per John's advice above, I will leave the exterior plastic fuel lines alone. But I'm interested in knowing how you replaced your external fuel line? I have none of the special tools necessary to replace the lines with original types. Did you use some other type of line?

    The replacement line comes with the elbow already in place together with the connections to the fuel injectors. Very simple to replace as a unit

    Forgive my never-ending questions on the subject, but is the elbow now a separately replaceable unit from the fuel pump? At one time, if you broke that elbow or wanted to replace it, you had to buy a new fuel pump with it .... ?

    Hi Lannis, yes it sure is. You'll find it on a search here on this Forum.
