leaking petrol tap

[Ethelred]

I've got a leaky tap, it's an age thing ;-). I've read a number of the old threads on here regarding the Ewarts taps, very interesting. I really don't fancy being reliant on cork seals for something so potentially dangerous and as I'm not an originality fanatic, I was about to replace them with something a bit more modern, but then I came across this:

Synthetic rubber replacement for the cork. For the price it's got to be worth a punt. Anyone tried them?

Not tried them, but look worth a punt eh?

Those look great (I tried the cork'ed stuff once, it leaked after a short while, and then disintegrated and got small bits of cork in the carb\jets).

Looks Good

Now replaced by the supplier, havnt tested the new stuff yet

that seems a good idea, reasonable price last time I bought corks they weren't much cheaper and like A10gf I had the same problem, I'D recommend Paul GOFF  for replacement taps with no messing about, best wishes BobH.

I still use the corks in mine.  I found that you must keep some gas in the tank or the cork will shrink and then start crumbling.  I just make sure I always have some gas treatment in the tank to keep the gas from lacquering.

I think the A’s are ganging up on me or are scared I may take them out in a rain shower. The A7 developed a leaky petrol tap (main) on Saturday, so no spares available over bank holiday weekend. I read and read and search and searched and found a some advise to steam the old cork. Well did it, it swelled and sealed and still is. Don’t know how long it will last, so will buy a spare this week but a quick fix that allowed a nice ride during a sunny spell  .

It is almost a routine job on the m20.
Boiling the petrol taps.

As for the rubber "corks"
I would be inclined to pop them in some "fuel" in a sealed glass container and leave them in a warm spot for a couple of days and see how they cope.
There is only 3 grades of rubber that are truely petrol proof.
There are a a lot more that are "petrol resistant", these will go soft after a few days in the sun.
AFAIK only teflon ( and its derivatives ) are both ethanol proof and petrol proof.

I put new corks in my Flash and they've been in about twelve years without problem, the RGF  has those BAP type ( as seen in the bottom of the  ebay listing )
the first ones stopped flowing as the rubber had swollen, the ones in now seem ok apart from the tap bit has turned a shade of brown - rust - after two years?

had the same problem with pipe chaterlea25

 Ethelred excuse me borrowing your post but does anyone know the thread on the bottom of the Ewarts tap (for the domed nut) I have one brass and one galvanised one, can't be seen both at once but I've a touch of CDO

One year and a month on since my last post on this thread and I'm chuffed to report the taps from paul still working well infact didn't lose a drop over the winter would still recommend them . For the corks I used to use soapy water and kept a supply immersed so I could just switch when they started to leak. BobH
