Ewarts fuel taps.

Got my taps back from Prestige Plating at the weekend. Problem is that the filters have basically disintegrated. Is there another filter on the market that I could fix to the top? Were these soldered on in the first place?
Suppose the easiest option would be an inline filter?

Any thoughts / advice?

Ewart taps

The filters are brass, soldered.
An in-line filter is by far the easiest way, but not pretty. My twin has had in-line ball valves intended for natural gas, and no filters, for two or three years. However I lined the tank with a product I bought from Frosts called something like K9P. It gives a finish that looks like silver Hammerite, and makes it easy to see inside the tank. My experience is that it is best to leave the tap holes open (ignoring the instructions...) to avoid a pool of liner there, then clean the thread out with a tap once it has set.
Something else that works is to push a bit of tube into the tap body so that there is always 1/2" of fuel left in the tank where nasties can lurk but not escape via your carburettor.

You can make the filters out of mesh/gauze, like a cigarette shape. It's a little tricky because you have to solder along the tube then solder the end by making it into a X shape.

I used a pencil as a former and made a ring of solder around the lower end to enable the filter to fit into the tap. My taps had an internal, very fine, thread and the filter just wriggles in to the tap.

I do have a small piece of filter material if you require some.

Don,
Thanks for the reply and the offer. Can you remember where you bought the filter material from?

Ewart taps

There's information in KTB on this, and this months VMCC Journal has a two-page article. One tip not given is to use corks from SPARKLING wine bottles, because the cork is very much denser than normal. If you needed an excuse to buy a bottle of Veuve Cliquot, you've got it.
I gave up on Ewart taps having refurbished them several times with no success, in favour of mini-ball valve (natural) gas taps from Plumb World, at a bargain £4 each. End of leaky taps saga...
Glad this came up , I need to sort out a few Ewarts taps.

Those Ewarts taps can certainly be a pig to refurbish. One thing that helps with the corks is to soak them in Castor Oil, available from most Chemists. It does not last long though.

I'm currently running a pair of taper cock taps, new stock, which will last for a little while before they either sieze up or start to leak. They don't answer to lapping in very well because of the hole in the taper makes the lapping in unequal.

If you do have them it pays to exercise them or they will sieze up, which I found out when trying to go on to reserve, in the dark, a few years ago. It took much banging on the small end to free it up.

As has been said the Gas Cocks seem to be the way to go, those who have fitted them say they work and last a long time.
