Lancia Motor Club

The rubber seal on the inside of my original petrol cap has become guey and shiny and peels away easily. Is this the end of the life of the cap? Or can it be fitted with a new seal? If a new cap is now needed are they easily obtainable?
Thanks you for any help,on this topic.

My Flavia coupe failed the MOT on the petrol cap rubber seal....somewhere in the Viva Lancia was an article showing how to dismantle the cap and replace the seal

v difficult to replace the rubber. I too remember seeing an article in VL but not sure if it was for the early Flavia type. New ones (old stock) were available at the Padova show last year if you looked hard but at a price. I bought one as my Vignale cap was going goey too.

I believe it is possible to rebuild the petrol cap if you have access to a lathe to make a new cental retaining stud.

Is this another case of "modern fuel, rubber doesn't cope" or just age?

Any chance of a photo as its possible I have one squirrelled away.

Thank you to all for your help.
The people in Norfolk I have learned can refurbish the cap with 3mm thick nitrile rubber for about £30. The secret is as many of you have pointed out is the re-riveting of the brass stud and spring assembly. This they say they can do.
My car has been standing for 13 years or so with little use so constant exposure only to petrol fumes has not helped. I suppose a little oil on the rubber would keep the newer petrol and its additives away from the (wait for it) perishing rubber!
Thanks again for the help.
 

Found the article...

I have this cap in my store, which can be disassembled. Not sure which model it would fit. Not Flaminia though

38 litre is Fulvia (S2), may fit Flavias too.

Flavia 815's are screw not bayonet.

Re Omicron - 3mm is rather thick?

That's a Fulvia Richard.
I offered Colin what I had which I think is Aurelia B20 S1/2 (Photos attached)?
He has decided to go to Omicron.
 I am quite surprised Lancia didn't use Fulvia and Flavia commonality/
Chris

Chaps,

I sent my cap to Omicron last week as the seal had also gone all gooey, and as Colin had suggested that it would cost about £30.00 thought nothing of it.


Be warned,  It arrived back today all repaired with a new seal and a bill for £137.72 !

Wow!!
I was told that the nitrile rubber was about £5-6 and that a new centre “rivet”would be made and peened over. How the cost can escalate like this I do not know.
Bob, so sorry to hear this tale.
Colin

Seems the new one I bought at Padova last year for 120eu was a bargain then! Didn't feel like that at the time....

Brian Long is correct, I don't know when but Fay's cap has had the centre rivet holding everything together, has been replaced with a threaded pin with a nut and washer on the underside.
 I replaced the seal, supplied by Omicron myself sometime ago with a new one by simply taking it apart.
Anyone got a lath, make a small fortune making these for £10 a time.

I have just refurbished 2 Flavia/Aurelia screw type caps by carefully releasing the peened over brass rivet, cleaning all parts, blind drilling the center to take an M4 tap and using a stainless dome headed cap bolt and washer with hard locktite to hold it all together, after replacing the rotten rubber (or cork) with a disk of 2mm nytrile (as per the article in VL). I dont have a lathe and all all the parts were "on the shelf" - so a free upgrade....

Additionally you need to file/grind the top of the unpeened rivet flat...

I'm just a tight Yorkshire man and I thought Omicron wanting £30 to replace the seal was 'Ow Much!' but £137 is just as JCS would say robbery with violence.

get one from http://www.amadeiricambi.it/lancia/lancia_flavia_815/motore___engine.html

And the price??? I believe these sellers only do business face to face and will not ship directly to UK.....

We shall see Tim, I've just requested the cost of the Series 1 Sedan heater motor and cost to send to me in the UK.

I have been dealing with him and other italian suppliers for years and there is no problem to ship to UK.

Also https://www.autoepoca.it/ have them on their website.

those dont have the litri plaque.....

ref cap shown reply no 8, the bayonet style is fitted to my Flavia 2000 Coupe 1970, albeit with 55 litre capacity plate. I know as I've just snapped off one half of the bayonet. Haven't yet managed a left turn at enough speed to persuade the fuel that far back up the filler pipe as it hasn't leaked yet. Will keep trying...
