Sorting thro my taps (what else to do?) I find a single plunger main and reserve with filter in perfect condition. The only problem is that the tank thread is smaller and finer than the bottom !/4 bsp. I'm thinking this is 1/8 bsp or gas. What tank would it fit? stamped Ewarts UK PAT 758264&ABROAD. I'm also sorting the late Atlas tap which looks like the double plunger type that Triumph fit, What did AMC fit at the end of production?
1/8 BSP Ewarts taps were used

1/8 bsp into tank.
Hi Nick,
I've fitted the modern tap and 90 degree outlet fitting listed on the NOC Shop.
The original Ewarts pull-for-on was so stiff it seemed to flex the bottom of the tank when opening. And it leaked after a while.
The rotary on-off in modern material is much better.
If anyone can find a similar rotary tap with reserve function to fit the Lightweight tank thread (1/8 BSP) let us know please. Not many bikes use this small thread. Bantams did. Other Nortons and most British are 1/4 BSP connection to the tank.
Happy riding
Peter
Cheers

Flat tank thread
Robert,
My 1927 Model 18 flat tank has a 1/8" BSP thread, so you can find a Model 18 as well as a Lightweight!

on the tanks of mid 50s singles, but the ones I'm familiar with have a banjo connection at the bottom and no reserve.
