Petrol tap repair

[AdrianS]

Been browsing on fleabay and noticed that someone in the states is selling some O rings to replace cork on petrol taps. Has anyone tried Viton O rings? Has it been successful? If so, what size was used?

did some a few years ago pre ethanol as I had a good supply of rings,  also got a supply of corks but not used many as tend to change taps as well due to having to soak the corks which used to tear. you could try
https://www.ebay.co.uk/itm/Ewarts-Petrol-Tap-Viton-O-Ring-Conversion-Kit-Austin-7-and-some-Vintage-Bikes-/174149654221
but he does say about worn bores , and I wonder about being ethanol proof after fuel ate away rubber hose and brass insides on my BSA A12 and Triumph T100 taps

I thought Viton was ethanol proof

has it been proved?
how much ethanol 5% or 20% in the future?
how long ? is 2 years long enough to say it  will last 20 years?

in my mind the jury is still out..

I thought corks were ethanol proof.  Had no problem so far even with occasional use of E10.  Never soaked corks prior to fitting just a bit of grease to help them slide in.  The taps do wear so do not expect perfect result in a very worn tap even with a new cork. If storing the bike without fuel then remove the taps and leave them in some oil in a sealed container.   This stops the corks drying out.

A similar o ring solution was covered in another britbike forum. Here is the link.

The problem is the o rings get cut or nicked when they pass the small hole in the barrel of the tap.

we will stick to corks then!
