I tossed that leaking mess a long time ago, but I don't care about being original. These, and similar, are all over the place, including ebay. For 16mm threads. MikeV

Happy New Year fellow Ducatisti! My F1 is hibernating nicely during the cold and wet Bay Area winter but before I'll be able to ride her again I will need to replace or repair the fuel tap which began to leak after my last ride last summer. I have not removed or inspected it, but it appears that a seal inside the tap (on the right side of the tank) has failed as its dripping fuel even when turned off. I've done only a little searching for a replacement, but it appears that the F1 fuel tap is unique to the model, and that the Pasos used a different part. I'm curious if anyone else here has replaced or repaired the tap on their F1 and if so, where they sourced the required parts. I've not yet reached out to Ian but I suppose I should do. Ciao! -tj in los gatos |

I think you'll find what you need at Bevel Heaven. I did. Bill https://store.bevelheaven.com/Taps |

Thanks both of you for the helpful responses. I was under the impression that the basic fuel taps as illustrated were an option. For some reason I thought the threads and fitting were of a different style and size. Ciao! -tj in los gatos |

Hi - I had reason to dismantle my fuel tap some time ago, not due to a fuel leak but owing to it becoming very hard to turn on. I seem to remember it being very easy to strip - I think I had to unscrew the lever from the spindle in order to remove the plastic ring to gain access for disassembly. The rubber disc inside is probably the sealing element which has failed and will require replacement. (Can't remember now if there was an o-ring fitted to spindle - if there is, this should also be replaced, again with Viton.) I have recently made new sealing discs for the (bevel single type) tap fitted to my old race-bike and its a very simple job. You need to measure the thickness of the old disc and obtain some Viton rubber sheet of the same dimension or slightly thicker ( I use 2mm for the bevel type taps). Mark the outline of the old disc (biro) onto the new material including the small diameter holes (3? - can't remember how many!). You can cut the outer diameter with small scissors and use a wad-punch to make the small holes - very easy! Good luck if you decide to go this route. I found that adding a shot of "Redex" to the fuel seems to stop these taps from seizing-up. Richie.

I used those types for years because they are light and flow well enough, salvaged some from 650 Alazzurra salvage ops and used a spritz of lanolin-based anti-rust lube to keep them perfectly functional for years. Ethanol in NA fuels attacks the poor wee things so some lube is really necessary. These are relatively easy to find and what you've pictured matches the Alazzurra taps I think a variation on Brev-Orlandi. I now use Pingles. A revelation but that's just function prioritised over form. Cheers, fmcd |

Hi - I realised I gave you some duff information regarding making new washers for your fuel tap (it was some time ago and my memory must have played tricks on me!). So I felt duty bound to revisit my own fuel tap which is indeed the same as F1. If you don't manage to find an equivalent you can strip your tap - but with some difficulty. That's the good news - the bad is that if the conical seating inside (nylon??) is broken up I can't see much can be done with it. I see that you've tapped out the operating pin and removed the plastic bezel. What you see underneath is where the body has been "staked" in 4 places to hold the valve block in place - you need to remove the indented metal. I did this by using a small, sharpened screwdriver, tapped vertically into the recess to push the deformed metal out. If you have access to some small enough diamond points you could carefully grind out the metal. In my case the valve assembly did not want to come out easily so I persuaded it with the body between 2 blocks of wood and a bar through the spindle and prised it out with 2 screwdrivers (there is very strong spring inside so it may take off when it suddenly finds its freedom!). Inside its very simple - just a conical metal plug valve running in a plastic liner. If the liner's broken up then I think you've had it - if not you may be lucky and it may work again with a cleanup. Not put mine back together yet but do not envisage any problems. May think about Epoxying the valve assembly back in and re-staking the body away from the original stakes. I hope this helps - sounds like you've not much to lose in dismantling it if its leaking badly - better still, find those Cagive alternatives!
