I have a double plunger ewarts tap on my WNG.
The threads are 7/16" (@11mm) across, which is not a BSP thread size ? This appears to be between 1/4" and 1/8", according to the BSP tables ...
I am struggling to find a fuel spigot and new nut for it ..

Re: Ewarts tap - output thread
There's a 3/16" option, Bantams use it; it's just not so common. The OD is nominally 10.8 mm. In fact I have one of those double plunger taps with a 3/16" outlet.
Often, thread tables you see online show only the preferred or most common sizes - the actual standard will have many more.

I have an Ewarts double plunger with the 3/8" BSP tank and 3/16" BSP output thread as discussed above.simon.holyfield wrote: ↑Mon Aug 15, 2016 2:48 pm There's a 3/16" option, Bantams use it; it's just not so common.

Did anyone solve the problem of where to get a suitable solder nipple and nut so that I can modify the fuel line (currently has 1/4" bsp fittings)?

Try Cotswold Engineering Supplies. They have an on-line shop but their website is a bit clunky.
