I've not installed it yet. The next time the tank must be removed, I'll make the swap. Yes, using FI hose and clamps. I see no reason it should work its way off, once installed.

I took the advice that krglorioso gave and used safety wire as an extra measure of precaution to ensure that the clamped fuel line on the red nipple could not slip over a period of time.  He's done this on two Guzzis and one has been on for around three years with zero slippage or leaks so it obviously works well.  Only takes a few minutes to add the safety wire while the tank is already off and it gives me "peace of mind" to have it on there.  My connectors arrive tomorrow so all I have to do to complete the project is screw them into the line that I've already installed, clamp them and snap the connectors together. 
If I bought another Guzzi that had this crummy connector on it, I would immediately replace it with this setup. It's worth the time & cost of materials to replace the inferior, factory connectors.

I'll mention my fix for the problem, which is that given where it lives, you can't grasp the fitting properly to get it off.  So I cut my fuel line in a more accessible place and installed marine grade fuel line quick disconnects.  They work like air hose couplings except both sides self-seal for dripless operation -- no pressure relief needed.  If you've got an old outboard motor tank and hose kicking around you already have the parts.

PS:  I used a 10" length of 8mm EFI hose running from the red elbow to the EXTERNAL fuel filter (all metal Mahle KL-145, I believe) and this places the filter in the space under the upper frame rails, where I wrapped it with a short piece of pipe insulation so it's not banging around on any neighboring pipe or frame rail.  I shortened the OEM fuel hose by about 10" and connected the outlet end of the filter there. Usual safety wire.  I can easily raise the tank and slip off the quick connector with one hand, patting myself on the back vigorously with the other!

Solving one problem, I created another - luckily this doesn't always happen!  Had to work on replacing the distintegrated switch for my fog lights on the Norge (was getting intermittent performance on/off of the lights) and decided that taking the tank off to check the wiring and relays was a good idea.  Good news, fog lights are working again and no crimping found, relay working well, and some re-routing of the wiring is done.  Check!

Bad news - I have now joined the fuel disconnect "Broken Red Elbow" club of esteemed colleagues above!  Thanks to this post, replacement parts from Gutsibits are on the way (ordered 2 just be on the safe side plus the pump gasket).  At least I was able to confirm in the process that I had already had the solid fuel filter installed and not the old plastic bloated one, and all else looks good.

Now I need get some padding to replace the foam under the tank, is that even a Guzzi part # or have folks just fabbed up some of their own padding with 3M adhesive and foam rubber?

Hi Chris...I ordered the red elbow which sits at the bottom of the pump on the outside of the tank, it's snugged in to pump and then held in place by a worm/grub hex screw, and the pump gasket, both from Gutsibits.

Here's the linky:

http://gutsibits.co.uk/pr/TheShop/index.php?f=e&Shnew=1&Model=2&ModelName=Breva%201100,%201200%20Sport,%20Norge,%20Griso,%20Stelvio&Cat=FUA&CatName=Fuel%20and%20Carburettors&spPage=3#topbar

Page 1 of this shows the rubber pump gasket - check that your fuel pump model is part number 05107230 on the fuel pump flange, if so, this gasket is for you.

Page 3 shows the Elbow...Gutsibits sells it in white, yours should be red if it had never been replaced before. 

Helluva a deal...pay 26 GBP for the elbow, or shell out 500 GBP for the pump, not sure what the pump costs stateside.  Cheap insurance...I bought 2 of them!

The CPC metal connectors are far better than the fragile plastic type but one thing to be aware of with them is the type of 'O' ring. As standard they supply them with a Nitrile 'O' ring which is not fuel resistant.


I fitted them to my Ducati 916 tank and they were fine for a year or so but the Nitrile rings swell in fuel and so those on the hose fitting split or leak - not a big problem as Viton 'O' rings are easily available, cheap and easy to change (in fact it's wise to change them regularly as it's easy to 'pinch' them, then they leak).

But the 'O' ring inside the tank fitting was also nitrile and when this swelled it cut off the fuel supply, leaving me stranded at the road side.

When I got the bike home it took me a while to figure out what was wrong as disconnecting/reconnecting the fittings made it work again (at least for a mile when it broke down again and I ended up nearly having a cardiac 'incident' pushing it home).

But to change the internal 'O' ring on the female fitting requires removal of the fitting from the tank which is a bit of a game due to the access and tapered threads on the fitting meaning they are tight.

Moral of the story is make sure the fittings (particularly the female) have Viton 'O' rings - CPC part number has the suffix 'V' if they are viton. or, if they don't have them in stock with Viton (they didn't when I contacted them) then order some Viton 'O' rings and change them before use. If in any doubt then change them anyway as swapping the 'O' ring in the tank fitting is a PITA if the fitting is in the tank.

The above info relates to a Ducati and so may not be relevant to Guzzi and I don't know if Guzzi use the same part? as there are NPT or BSP threads? but for info the NPT thread as used by Ducati has the following CPC part no.

CPC -  LCD10004V = Metal female with viton seal

The hose fitting is;

CPC - LCD23006V = Metal male with viton seal 

If they only have the same part without the 'V' at the end then assume the 'O' ring is not Viton and get some ath the same time as the fitting, in fact get some spares as the ones on the hose attachments will need changing at some point anyway.

Hi-

 Just making sure, this would be the correct disconnect for a '07 Breva 1100?

    I, like many others, was going crazy trying to remove the quick disconnect (oxy moron!) fuel coupling on my 2008 CalVin. The thing literally brought me to my knees, and I was deathly afraid of breaking the plastic piece of crap.

    I apologize, I don't have the link,,, but I think it was the owner of a Breva? who had posted 2 different videos on Youtube, on how to remove the MG fuel line disconnect, that solved the mystery for me,,, patience is a virtue,,, once I figured it out,, it was a simple one hand removal,,, I've probably put the hex on it for future removals, bwth,,,lol.

    From the video, and what worked for me,, was grabbing the outer female part of the coupling between my thumb and middle fingers,,,push the coupling forward, and while maintaining forward pressure,,, putting tips of my thumb and index finger, using them as slight wedges pushing backwards as I wiggled it slightly back and forth.

    Once I mastered this simple one handed technique,,, what had previously, frustrated me for hrs, became a 5 second damage free removal, I didn't have to relieve pressure in the line or jump through any hoops.

    After seeing how simple and well the right technique worked,,, I would be extremely hesitant about using any tpe of tool around those fragile , brittle plastic bits.

     As always, ymmv fwiw,,,

     Good luck

US buyers may want to check Amazon - the sellers there are also in the UK, but some offer less expensive and faster shipping to the US. As always, with any foreign source the reviews become very important!

I'm puzzled that no one seems to offer these things in the US - we're saddled with the klutzy designs instead!

I bought a set of those pliers style tools. Didn't work for me except to use them as a way to grip the QD fitting.

What has worked so far is to lift back of tank, disconnect the fuel pump electrical connector, start the bike and let it run out to relieve the fuel pressure and the QD comes off with a bit of a wiggle. HD tells you to do this same thing for their QD connector.

Seems to work??

I'm hoping that these little tools will make handling this contraption a little easier...almost like you need a 3rd pair of hands at the moment to squeeze in the gray tabs and then wiggle that bugger off the red nipple....will see once the replacement item comes in.

Thanks for all the inputs here guys.
