What size/type is the thread in the bottom of the petrol tank for the petrol tap go into?
I need to clean my threads and want to run a tap through them.
Secondly, I need some fuel taps, where to go to buy some?
Original part no. 17907

Alun the tread size both ends would normally be 1/4 BSP. Ron

I'll double check what holw size is on the tank and order some new petrol taps. The ones I ordered before are the wrong size (too large).
I know you said 1/4BSP both sides, I've found those available, as well as 1/8BSP in with a 1/4BSP out.
What fuel tank would use 1/8BSP?
The BSA WM20's were originally fitted with taps that had an 1/8 bsp thread both ends. Lots have been converted over to 1/4 x 1/4 now though.
For reference, a 1/4 BSP thread has an actual outside diameter of 1/2".... 1/8 BSP is 3/8"
Hi there Alun
R.e. WD G3L petrol tank taps. Just measured the taps on my WD G3L & the inlet (Filter end) is 1/8 BSP While the outlet thread is 1/4 BSP.
